• 65349d60d   mfd: Convert MFD drivers to use module_platform_driver ... Browse Code »

  Factors out some boilerplate code for drivers doing the default thing
  for platform driver registration. Drivers using platform_driver_probe
  or an initcall other than module_init can't be converted.

  If the twl4030-madc device wasn't registered, and another device, such
  as twl4030-madc-hwmon, calls twl4030_madc_conversion() a NULL pointer is
  dereferenced.

  Worst case this fixes the following error:
  [ 72.086212] (NULL device *): conversion timeout!

  Best case it prevents a crash

• e178ccb33   mfd: Fix mismatch in twl4030 mutex lock-unlock ... Browse Code »

  1

  A mutex is locked on entry into twl4030_madc_conversion().
  Immediate return on some error conditions leaves the
  mutex locked.

  This patch ensures that mutex is always unlocked before
  leaving the function.
