* pwm: drop owner assignment from platform_driversWolfram Sang2014-10-201-1/+0
| | | | | | | A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* pwm: Fill in missing .owner fieldsThierry Reding2013-06-121-0/+1
| | | | | | | Some drivers don't set the .owner fields of the struct device_driver or struct pwm_ops, which causes the module usage count to become wrong. Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
* pwm: remove use of __devexitBill Pemberton2012-11-281-1/+1
| | | | | | | | | CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Acked-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* pwm: Check for negative duty-cycle and periodThierry Reding2012-10-051-3/+0
| | | | | | | | | | | | | | | | | | | | | Make sure the duty-cycle and period passed in are not negative. This should eventually be made implicit by making them unsigned. While at it, the drivers' .config() implementations can have the equivalent checks removed.
