  • f7bd7b545   hwmon: (f75375s) use simple i2c probe ... Browse Code »

    As part of the ongoing i2c transition to the simple probe
    ("probe_new"), this patch uses i2c_match_id to retrieve the
    driver_data for the probed device. The id parameter is thus no longer
    necessary and the simple probe can be used instead.

    In some configurations, BUG() does not result in an endless loop but returns to
    the caller. This results in the following compiler warning:

    drivers/hwmon/f75375s.c: In function 'duty_mode_enabled':
    drivers/hwmon/f75375s.c:280: warning: control reaches end of non-void function

    drivers/hwmon/f75375s.c:295: warning: control reaches end of non-void function

    Fix the warning by returning something sensible after BUG().

    It makes no sense to attempt to manually configure the fan in auto mode,
    or set the duty cycle directly in closed loop mode. The corresponding
    registers are then read-only. If the user tries it nonetheless, error out
    with EINVAL instead of silently doing nothing.

  • b17d6561a   hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enable ... Browse Code »

    The F75387 supports automatic fan control using either PWM duty cycle or
    RPM speed values. Make the driver detect the latter mode, and expose the
    different modes in sysfs as per pwm_enable, so that the user can switch
    between them.

    The interpretation of the pwm_enable attribute for the F75387 is adjusted
    to be a superset of those values used for similar Fintek chips which do
    not support automatic duty mode, with 2 mapping to automatic speed mode,
    and moving automatic duty mode to the new value 4.

    Toggling the duty mode via pwm_enable is currently denied for the F75387,
    as the chip then simply reinterprets the fan configuration register values
    according to the new mode, switching between RPM and PWM units, which
    makes this a dangerous operation.

    This patch introduces a new pwm mode into the driver. This is necessary
    because the new mode (automatic pwm mode, 4) may already be enabled by the
    BIOS, and the driver should not break existing functionality. This was seen
    on at least one board.

    1

    By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan
    to full speed. In the f75375s driver, this need be done by enabling
    manual fan control, plus duty mode for the F875387 chip, and then setting
    the maximum duty cycle. Fix a bug where the two necessary register writes
    were swapped, effectively discarding the setting to full-speed.

  • fbae3fb15   i2c: Remove all i2c_set_clientdata(client, NULL) in drivers ... Browse Code »

    I2C drivers can use the clientdata-pointer to point to private data. As I2C
    devices are not really unregistered, but merely detached from their driver, it
    used to be the drivers obligation to clear this pointer during remove() or a
    failed probe(). As a couple of drivers forgot to do this, it was agreed that it
    was cleaner if the i2c-core does this clearance when appropriate, as there is
    no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
    This feature was added to the core with commit
    e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

    As there is no need anymore to clear the clientdata-pointer, remove all current
    occurrences in the drivers to simplify the code and prevent confusion.

  • 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.

  • 51b3e2700   hwmon: (f75375s) Remove unnecessary and confusing initialization ... Browse Code »

    f75375_probe calls i2c_get_clientdata to initialize the data pointer,
    but there isn't yet any client data to get, and the value is never
    used before the variable is assigned a new value seven lines later.

    The call doesn't hurt anything and wastes only a couple of cycles.
    The reason to fix it is because this module serves as an example to
    hackers writing new hwmon drivers, and this part of the example is
    confusing.
