• 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.

• 6f6b35e13   macintosh: Don't assume i2c device probing always succeeds ... Browse Code »

  If i2c device probing fails, then there is no driver to dereference
  after calling i2c_new_device(). Stop assuming that probing will always
  succeed, to avoid NULL pointer dereferences. We have an easier access
  to the driver anyway.

• 80ff974db   [POWERPC] windfarm: Add PowerMac 12,1 support ... Browse Code »

  This implements a new driver named windfarm_pm121, which drives the
  fans on PowerMac 12,1 machines : iMac G5 iSight (rev C) 17" and
  20". It's based on the windfarm_pm81 driver from Benjamin
  Herrenschmidt.

  This includes fixes from David Woodhouse correcting the names of some
  of the sensors.

  This is just a straight replacement.

  This leaves the compatibility define in place.

• b55fafc5a   [PATCH] powerpc: Fix old g5 issues with windfarm ... Browse Code »

  Some of the windfarm sensor modules can initialize on old machines that
  don't have full windfarm support like non-dual core desktop G5s.
  Unfortunately, by doing so, they would trigger a bug in their matching
  algorithm causing them to attach to the wrong bus, thus triggering
  issues with the i2c core and breaking the thermal driver.

  This patch fixes the probing issue (so that they will work when a
  windfarm port is done to these machines) and also prevents for now
  windfarm to load at all on these machines that still use therm_pm72 to
  avoid wasting resources.

• 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.
