Hello Srinivas Kandagatla,
Commit 378918d59181 ("ASoC: codecs: lpass-macro: add helpers to get codec version") from Jun 13, 2024 (linux-next), leads to the following Smatch static checker warning:
sound/soc/codecs/lpass-va-macro.c:1485 va_macro_set_lpass_codec_version() error: uninitialized symbol 'version'.
sound/soc/codecs/lpass-va-macro.c 1464 static void va_macro_set_lpass_codec_version(struct va_macro *va) 1465 { 1466 int core_id_0 = 0, core_id_1 = 0, core_id_2 = 0, version;
We could just initialize this to zero to make the checker happy? The compiler is generally going to zero it anyway so it's free.
