2016-01-04leds: Rename brightness_set_sync op to brightness_set_blockingJacek Anaszewski
The initial purpose of brightness_set_sync op, introduced along with the LED flash class extension, was to add a means for setting torch LED brightness as soon as possible, which couldn't have been guaranteed by brightness_set op. This patch renames the op to brightness_set_blocking, which describes its purpose in a more generic way. It is beneficial in view of the prospective changes in the LED core, aiming at removing the need for using work queues in LED class drivers that can sleep or use delays while setting brightness.

2015-07-16drivers: max77693: Move state container to common headerKrzysztof Kozlowski
This prepares for merging some of the drivers between max77693 and max77843 so the child MFD driver can be attached to any parent MFD main driver. Move the state container to common header file. Additionally add consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).
