This serie contains 3 fixes for I²C error handling cases.
It also includes a patch to get rid of the deprecated
dmaengine_terminate_all calls.

Alain Volmat (4):
  i2c: stm32f7: flush TX FIFO upon transfer errors
  i2c: stm32f7: recover the bus on access timeout
  i2c: stm32f7: stop dma transfer in case of NACK
  i2c: stm32f7: use proper DMAENGINE API for termination
