* backlight: convert from legacy pm ops to dev_pm_opsShuah Khan2013-07-031-3/+7
| | | | | | | | | | | | | | | | | | | | Convert drivers/video/backlight/class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, backlight class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the backlight class.

* drivers: avoid format string in dev_set_nameKees Cook2013-07-032-2/+2
| | | | | | | | | | | Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The brightness of LP855x devices is controlled by I2C register or PWM input . This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe(). Move 'mode' from a header file to the driver private data structure, 'lp855 x'. And correlated code was replaced.

| | | | | | | | | | | | | | | | | | | | regulator_enable() is marked as as __must_check. Therefore the return value of regulator_enable() should be checked. Also, this patch checks return value of regulator_set_voltage().

| | | | | | | | | | | | | | | | | | | | | | Add missing braces to include error message. The error message is related to the return value for sysfs_create_group(). However, sysfs_create_group() is called when pdata->en_ambl_sens is not zero. Thus, the checking return value should be included in the if statement.
