Merge tag 'extcon-next-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next
Chanwoo writes: Update extcon for 3.13 This patchset modify extcon core to remove unnecessary allocation sequence for 'dev' instance and change extcon_dev_register() interface. extcon-gpio use gpiolib API to get debounce time and include small fix of extcon core/device driver. Detailed description for patchset: 1. Modify extcon core driver - The extcon-gpio driver use gpio_set_debounce() API provided from gpiolib if gpio driver for SoC support gpio_set_debounce() function and support 'gpio_ activ_low' filed to check whether gpio active state is 1(high) or 0(low). - Change field type of 'dev' in structure extcon_dev and remove the sequence of allocating memory of 'struct dev' on extcon_dev_register() function because extcon device must need 'struct device. - Change extcon_dev_register() prototype to simplify it and remove unnecessary parameter as below: 2. Fix coding style and typo - extcon core : Fix indentation coding style and remove unnecessary casting - extcon-max8997 : Fix checkpatch warning - extcon-max77693 : Fix checkpatch warning - extcon-arizona : Fix typo of comment and modify minor issue - extcon-palmas : Use dev_get_platdata() 3. Modify extcon-arizona driver - Modify minor issue about micbias and comparision statement
