Subject: linux-next: build warning after merge of the sound-asoc tree

Hi all,

After merging the sound-asoc tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

sound/soc/stm/stm32_sai_sub.c: In function 'stm32_sai_hw_params':
sound/soc/stm/stm32_sai_sub.c:485:7: warning: 'cr1' may be used uninitialized in this function [-Wmaybe-uninitialized]
   cr1 |= SAI_XCR1_DS_SET(SAI_DATASIZE_8);
       ^
sound/soc/stm/stm32_sai_sub.c:469:6: note: 'cr1' was declared here
  int cr1, cr1_mask, ret;
      ^

Introduced by commit

  61fb4ff70377 ("ASoC: stm32: sai: Move static settings to DAI init")
