  • 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.

  • We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
    meet kernel coding style guidelines. This issue was reported by checkpatch.

    A simplified version of the semantic patch that makes this change is as
    follows (http://coccinelle.lip6.fr/):

    //

    @@
    identifier i;
    declarer name DEFINE_PCI_DEVICE_TABLE;
    initializer z;
    @@

    - DEFINE_PCI_DEVICE_TABLE(i)
    + const struct pci_device_id i[]
    = z;

  • 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.

  • Because currently snd_printd() and snd_printdd() macros are expanded
    to empty when CONFIG_SND_DEBUG=n, a compile warning like below
    appears sometimes, and we had to covert it by ugly ifdefs:
    sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’:
    sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable]

    For "fixing" these issues better, this patch replaces snd_printd() and
    snd_printdd() definitions with empty inline functions instead of
    macros. This should have the same effect but shut up warnings like
    above.

    But since we had already put ifdefs, changing to inline functions
    would trigger compile errors. So, such ifdefs is removed in this
    patch.

    In addition, snd_pci_quirk name field is defined only when
    CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in
    snd_printdd() argument triggers the build errors, too. For avoiding
    these errors, introduce a new macro snd_pci_quirk_name() that is
    defined no matter how the debug option is set.

  • CONFIG_HOTPLUG is going away as an option. As result the __dev*
    markings will be going away.

    Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
    and __devexit.

  • module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    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.

  • kcalloc is supposed to be called with the count as its first argument and the
    element size as the second.

    Both arguments are size_t so does not affect correctness. This callsite is
    during module_init and therefore not performance critical. Another patch will
    optimize the case when the count is variable but the size is fixed.

  • This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

  • Fix IRQ flags for PCI devices.
    The shared IRQs for PCI devices shouldn't be allocated with
    IRQF_DISABLED. Also, when MSI is enabled, IRQF_SHARED shouldn't
    be used.
    The patch removes unnecessary cast in request_irq and free_irq,
    too.

    in the suspend. If any error occurs there, disable the device
    using snd_card_disconnect().
    - Call pci_set_power_state() properly with pci_choose_state().
    - Fix the order to call pci_set_power_state().

  • Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.
