2017-08-14i2c: stm32f4: explicitly request exclusive reset controlPhilipp Zabel
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

2017-08-12i2c: constify internal structuresGustavo A. R. Silva
Check for i2c_algorithm and i2c_adapter_quirks structures that are only stored in the algo and quirks fields of an i2c_adapter structure correspondingly. These fields are declared const, so i2c_algorithm and i2c_adapter_quirks structures that have this property can be declared as const also. Signed-off-by: Gustavo A. R.
