build failure of next-20220822 due to 4e6bedd3c396 ("ASoC: codecs: add support for the TI SRC4392 codec")
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: ^~~~~~~ sound/soc/codecs/src4xxx.c:298:59: note: uninitialized use occurs here ret = regmap_write(src4xxx->regmap, SRC4XXX_RCV_PLL_11, d); ^ sound/soc/codecs/src4xxx.c:223:20: note: initialize the variable 'd' to silence this warning int val, pj, jd, d; ^ = 0 sound/soc/codecs/src4xxx.c:280:3: error: variable 'jd' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized] default: ^~~~~~~ sound/soc/codecs/src4xxx.c:293:59: note: uninitialized use occurs here ret = regmap_write(src4xxx->regmap, SRC4XXX_RCV_PLL_10, jd); ^~ sound/soc/codecs/src4xxx.c:223:17: note: initialize the variable 'jd' to silence this warning int val, pj, jd, d; ^ = 0 sound/soc/codecs/src4xxx.c:280:3: error: variable 'pj' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized] default: ^~~~~~~ sound/soc/codecs/src4xxx.c:288:59: note: uninitialized use occurs here ret = regmap_write(src4xxx->regmap, SRC4XXX_RCV_PLL_0F, pj); ^~ sound/soc/codecs/src4xxx.c:223:13: note: initialize the variable 'pj' to silence this warning int val, pj, jd, d; ^ = 0 3 errors generated.
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.

Hi Sudip, Thanks for the report. Two ways you can check if it's already been reported: 1. Check our issue tracker (https://github.com/ClangBuiltLinux/linux/issues), you'll see that it has been (https://github.com/ClangBuiltLinux/linux/issues/1691 -> https://lore.kernel.org/all/YvvbKry5FVFbNdcI@dev-arch.thelio-3990X/) 2. Search for the warning message on lore. (https://lore.kernel.org/all/ -> search for "sound/soc/codecs/src4xxx.c Wsometimes" -> https://lore.kernel.org/all/?q=sound%2Fsoc%2Fcodecs%2Fsrc4xxx.c+Wsometimes and you'll see two reports from bots and two from humans).
