After commit 61fb4ff70377 ("ASoC: stm32: sai: Move static settings to DAI init"), we get a valid warning about the use of an uninitialized variable:
sound/soc/stm/stm32_sai_sub.c: In function 'stm32_sai_hw_params': sound/soc/stm/stm32_sai_sub.c:485:7: error: 'cr1' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I could not immediately figure out what the code should do instead, this is the hack I applied locally to shut up the warning. It may or may not be correct, please take a look.
