  • 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.

  • 4b2643d7d   i2c: Fix the i2c_smbus_read_i2c_block_data() prototype ... Browse Code »

    Let the drivers specify how many bytes they want to read with
    i2c_smbus_read_i2c_block_data(). So far, the block count was
    hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense.
    Many driver authors complained about this before, and I believe it's
    about time to fix it. Right now, authors have to do technically stupid
    things, such as individual byte reads or full-fledged I2C messaging,
    to work around the problem. We do not want to encourage that.

    I even found that some bus drivers (e.g. i2c-amd8111) already
    implemented I2C block read the "right" way, that is, they didn't
    follow the old, broken standard. The fact that it was never noticed
    before just shows how little i2c_smbus_read_i2c_block_data() was used,
    which isn't that surprising given how broken its prototype was so far.

    There are some obvious compatiblity considerations:
    * This changes the i2c_smbus_read_i2c_block_data() prototype. Users
    outside the kernel tree will notice at compilation time, and will
    have to update their code.
    * User-space has access to i2c_smbus_xfer() directly using i2c-dev, so
    the changed expectations would affect tools such as i2cdump. In order
    to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA
    a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the
    old numeric value. When i2c-dev receives a transaction with the
    old value, it can convert it to the new format on the fly.

  • 018a3d1db   [POWERPC] powermac: Constify & voidify get_property() ... Browse Code »

    Now that get_property() returns a void *, there's no need to cast its
    return value. Also, treat the return value as const, so we can
    constify get_property later.

    powermac platform & macintosh driver changes.

    Built for pmac32_defconfig, g5_defconfig

  • 9127dd1aa   [PATCH] allow windfarm_pm112 module to load ... Browse Code »

    The windfarm_pm112 module relies on smu_sat_get_sdb_partition which is in
    windfarm_smu_sat.c but is not exported to modules, so despite Kconfig
    having the option to build the pm112 as modules, this can never be loaded.

    This patch fixes that by exporting smu_sat_get_sdb_partition with
    EXPORT_SYMBOL_GPL

  • ac171c466   [PATCH] powerpc: Thermal control for dual core G5s ... Browse Code »

    This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
    (both 2 and 4 core models), keeping the machine from getting into
    vacuum-cleaner mode ;) For proper credits, the patch was initially
    written by Paul Mackerras, and slightly reworked by me to add overtemp
    handling among others. The patch also removes the sysfs attributes from
    windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
    core to automagically expose attributes for sensor & controls.
