* hwmon: (pmbus) Simplify remove functionsGuenter Roeck2012-03-181-7/+1
| | | | | | | | | Since devm_kzalloc() is now used to allocate driver memory, the client driver remove function has no purpose other than to call pmbus_do_remove(). This means we can get rid of it by redefining pmbus_do_remove() to use the same prototype, and pointing to it directly. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (pmbus) Convert pmbus drivers to use devm_kzallocGuenter Roeck2012-03-181-14/+3

* hwmon: convert drivers/hwmon/* to use module_i2c_driver()Axel Lin2012-03-181-11/+1
| | | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/hwmon/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

* hwmon: (pmbus) Don't return errors from driver remove functionsGuenter Roeck2011-10-241-3/+2
| | | | | | | | | | | | | | | | | | | | | Driver remove functions have an error return value, but rarely return an error in practice. If a driver does return an error from its remove function, the driver won't be unloaded and is expected to stay alive. pmbus_do_remove() is defined as returning an int, but always returns 0 (no error). Calling code passes that return value on to high level driver remove functions, but does not evaluate it and removes driver data even if pmbus_do_remove() returned an error (which it in practice never does). Even if this code could never cause a real problem, it is nevertheless conceptually wrong. To reduce confusion and simplify the code, change pmbus_do_remove() to be a void function, and have PMBus client drivers always return zero in their driver remove functions.

* hwmon: (pmbus) Add support for VID output voltage modeGuenter Roeck2011-07-281-3/+31
| | | | | | | | | | | | In VID mode, output voltages are measured and reported as VID values, and have to be converted to voltages using VID conversion tables or functions. Support is added for VR11 only at this time. This patch enables support for PMBus devices supporting VID VR11 based output voltage selection such as NCP4200 and NCP4208.
