[Linux-stm32] [PATCH] i2c: stm32f7: remove noisy and imprecise log messages

[Wolfram Sang]

The log messages talk about 'bus recovery' while it is not a bus
recovery with 9 pulses but merely a controller reset. Controller resets
are not worth log messages. The 'bus busy' message should be emitted by
upper layers, a busy bus may be expectected in some cases.

Alain, do you agree? Only compile tested.
