Clang warns (or errors with CONFIG_WERROR=y):
sound/soc/codecs/aw88399.c:441:18: error: variable 'vsense_select' is uninitialized when used here [-Werror,-Wuninitialized]
441 | vsense_select = vsense_select & (~AW88399_VDSEL_MASK);
| ^~~~~~~~~~~~~
sound/soc/codecs/aw88399.c:431:28: note: initialize the variable 'vsense_select' to silence this warning
431 | unsigned int vsense_select, vsense_value;
| ^
| = 0
1 error generated.
This clearly should have been using the value received from
regmap_read(). Use the correct variable to resolve the warning.
