  • Currently, sound device drivers for PCI cards produced by Echo Audio
    support dimension parameter of element information. But the information
    has contradictions to the number of members of each element. I guess that
    this comes from the assumption that these sound cards are used only by
    'echomixer' in userspace. But ideally, they should be used with usual ALSA
    control applications.

    This commit removes the contradiction. As a result, 'Monitor Mixer Volume'
    and 'VMixer Volume' elements are shown in usual ALSA control applications
    such as 'amixer' and 'alsamixer' in series.

  • 'commpage_bak' is allocated with 'sizeof(struct echoaudio)' bytes.
    We then copy 'sizeof(struct comm_page)' bytes in it.
    On my system, smatch complains because one is 2960 and the other is 3072.

    This would result in memory corruption or a oops.

  • The echoaudio locally defines TRUE and FALSE. Not only is this
    redundant given that C now has a boolean type it results in lots of
    warnings as other headers also define these macros, causing duplicate
    definitions. Fix this by removing the local defines and converting all
    local users to use the standard C true and false instead, simply
    removing the macros is less safe due to implicit inclusion of the other
    definitons.

  • We need to cap "ucontrol->id.index / num_busses_in(chip)" so the we
    don't read beyond the end of the array.

    I also adding a check on "in" and changing the type in
    snd_echo_mixer_put() from short to unsigned int. Those changes are done
    for symmetry and are cosmetic.

  • This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801:
    PCI core handles power state for us].

    Since pci_set_power_state(), pci_save_state() and pci_restore_state()
    are already done in the PCI core side, so we don't need to it doubly.

    Also, pci_enable_device(), pci_disable_device() and pci_set_master()
    calls in PM callbacks are superfluous nowadays, too, so get rid of
    them as well.

  • commit "b5b4a41b392960010fccf1f9ccf8334d612bd450" was dereferencing
    chip after it has been freed. This patch fixes that and at the same
    time removes some debugging messages, which are unnecessary, as they
    are just printing information about entry and exit from a function,
    and which switch-case it is executing.
    we can easily get from ftrace the information about the entry and exit
    from a function.

  • As drvdata is cleared to NULL at probe failure or at removal by the
    driver core, we don't have to call pci_set_drvdata(pci, NULL) any
    longer in each driver.

    The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
    hda_intel.c. Since this function itself releases the card instance,
    we need to clear drvdata here as well, so that it won't be released
    doubly in the remove callback.

  • This assertion seems to imply that chip->dsp_code_to_load is a pointer.
    It's actually an integer handle on the actual firmware, and 0 has no
    special meaning.

    The assertion prevents initialisation of a Darla20 card, but would also
    affect other models. It seems it was introduced in commit dd7b254d.

    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

  • The name argument of request_irq() appears in /proc/interrupts, and
    it's quite ugly when the name entry contains a space or special letters.
    In general, it's simpler and more readable when the module name appears
    there, so let's replace all entries with KBUILD_MODNAME.

  • The convention for pci_driver.name entry in kernel drivers seem to be
    the module name or equivalent ones. But, so far, almost all PCI sound
    drivers use more verbose name like "ABC Xyz (12)", and these are fairly
    confusing when appearing as a file name.

    This patch converts the all pci_driver.name entries in sound/pci/* to
    use KBUILD_MODNAME for more unified appearance.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • This patch fixes a division by zero error in the irq handler.

    There is a small window between the hw_params() callback and when
    runtime->frame_bits is set by ALSA middle layer. When another substream is
    already running, if an interrupt is delivered during that window the irq
    handler calls pcm_pointer() which does a division by zero. The patch below
    makes the irq handler skip substreams that are initialized but not started
    yet. Cc to Clemens Ladisch because he proposed an alternate fix.
