  • 1c703b53e   HID: input: fix a4tech horizontal wheel custom usage ... Browse Code »

    Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether
    the previous wheel report was horizontal or vertical. Before
    c01908a14bf73 ("HID: input: add mapping for "Toggle Display" key") this
    usage was being mapped to 'Relative.Misc'. After the patch it's simply
    ignored (usage->type == 0 & usage->code == 0). Which ultimately makes
    hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no
    usage->type.

    We shouldn't rely on a mapping for that usage as it's nonstandard and
    doesn't really map to an input event. So we bypass the mapping and make
    sure the custom event handling properly handles both reports.

    Fixes: c01908a14bf73 ("HID: input: add mapping for "Toggle Display" key")

  • abf832bfc   HID: trivial devm conversion for special hid drivers ... Browse Code »

    It is safe to use devres allocation within the hid subsystem:
    - the devres release is called _after_ the call to .remove(), meaning
    that no freed pointers will exists while removing the device
    - if a .probe() fails, devres releases all the allocated ressources
    before going to the next driver: there will not be ghost ressources
    attached to a hid device if several drivers are probed.

    Given that, we can clean up a little some of the HID drivers. These ones
    are trivial:
    - there is only one kzalloc in the driver
    - the .remove() callback contains only one kfree on top of hid_hw_stop()
    - the error path in the probe is easy enough to be manually checked

    Use the new module_hid_driver macro in all HID drivers that have
    a simple register/unregister init/exit.

    This also converts the hid drivers that test for a failure of
    hid_register_driver() and report the failure. Using module_hid_driver
    in those drivers removes the failure message.

  • 2f43f8749   HID: remove Paul Walmsley's copyright from places where it shouldn't be ... Browse Code »

    Paul Walmsley has implemented dynamic quirk handling back in 2007 through
    commits:

    2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c")
    8222fbe67c ("USB HID: clarify static quirk handling as squirks")
    8cef908235 ("USB HID: add support for dynamically-created quirks")
    876b9276b9 ("USB HID: add 'quirks' module parameter")

    and as such, his copyright rightly belongs to
    drivers/hid/usbhid/hid-quirks.c file.

    However when generic HID code has been converted to bus and individual
    quirks separated out to individual drivers on the bus, the copyright has
    been blindly transfered into all the tiny drivers, which actually don't
    contain any of Pauls' copyrighted code.

    Remove the copyright from those sub-drivers.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …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.

  • afa5eb7c6   HID: remove compat stuff ... Browse Code »

    This removal was scheduled and there is no problem with later
    distros to adapt for the new bus, thanks to aliases.

    module-init-tools map files are deprecated nowadays, so that
    the patch which introduced hid ones into the m-i-t won't be
    accepted and hence there is no reason for leaving compat stuff in.
