Poweroff the fans when shutting down the system.

2014-11-19hwmon: (g762) fix call to devm_hwmon_device_register_with_groups()Arnaud Ebalard1-4/+2
g762_remove() needs to first call hwmon_device_unregister() and then g762_of_clock_disable(). For that reason, it is not possible to convert it to devm_hwmon_device_register_with_groups() and the the non device managed version must be used. This is correctly stated in commit message for 398e16db6262 ("hwmon: (g762) Convert to hwmon_device_register_with_groups") but the associated changes do in fact introduce a call to the device managed version of the function. This patch fixes that typo by switching to the non devm_ version.

2014-11-11hwmon: (ibmpowernv) Quieten when probing finds no deviceMichael Ellerman1-2/+4
Because we build kernels with drivers built in for many platforms, it's normal for the ibmpowernv driver to be loaded on systems that don't have the appropriate hardware. Currently the driver spams the log with: ibmpowernv ibmpowernv.0: Opal node 'sensors' not found ibmpowernv: Platfrom driver probe failed But there is no error, this machine is not a powernv and doesn't have the hardware. So change the sensors message to dev_dbg(), and only print an error about the probe failing if it's not ENODEV. Also fix the spelling of "Platfrom" and print the actual error value.
