* hwmon: (applesmc) Check key count before proceedingHenrik Rydberg2013-09-26
| | | | | | | | | | | | | After reports from Chris and Josh Boyer of a rare crash in applesmc, Guenter pointed at the initialization problem fixed below. The patch has not been verified to fix the crash, but should be applied regardless.

* hwmon: (k10temp) remove unnecessary pci_set_drvdata()Jingoo Han2013-09-12
| | | | | | | | | | The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

The return code of i2c_smbus_write_byte_data() is zero for success. The upshot is only the first byte was ever written to the hardware. The 2nd byte was never written out. I noticed that trying to set the fan speed limits was not working correctly on my system. Setting the fan speed limits is the only code that uses adt7470_write_word_data(). After making the change the limit settings work and the alarms work also.

|/ | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the drivers/hwmon uses of the __cpuinit macros from all C files.
