2019-04-10ASoC: stm32: sai: fix master clock managementOlivier Moysan
When master clock is used, master clock rate is set exclusively. Parent clocks of master clock cannot be changed after a call to clk_set_rate_exclusive(). So the parent clock of SAI kernel clock must be set before. Ensure also that exclusive rate operations are balanced in STM32 SAI driver.

2018-11-13ASoC: stm32: sai: fix invalid use of sizeof in stm32_sai_add_mclk_provider()Wei Yongjun
