Hi All,
Not sure if it has been reported, builds of arm64 with clang failed to
build next-20220822 with the error:
sound/soc/codecs/src4xxx.c:280:3: error: variable 'd' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
default:

ret = regmap_write(src4xxx->regmap, SRC4XXX_RCV_PLL_11, d);

git bisect pointed to 4e6bedd3c396 ("ASoC: codecs: add support for the TI SRC4392 codec").
I will be happy to test any patch or provide any extra log if needed.
