ASoC: cs42l43: Initialize ret in default case in cs42l43_pll_ev()
clang warns (or errors with CONFIG_WERROR=y):
sound/soc/codecs/cs42l43.c:1371:2: error: variable 'ret' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
1371 | default:
| ^~~~~~~
sound/soc/codecs/cs42l43.c:1377:9: note: uninitialized use occurs here
1377 | return ret;
| ^~~
sound/soc/codecs/cs42l43.c:1349:9: note: initialize the variable 'ret' to silence this warning
1349 | int ret;
| ^
| = 0
1 error generated.
Initialize ret to 0 in the default case, as there was nothing to do for
other event types.
Closes: https://github.com/ClangBuiltLinux/linux/issues/1922
Fixes: fc918cbe874e ("ASoC: cs42l43: Add support for the cs42l43")
