[PATCH] leds: max77705: Function return instead of variable assignment
Posted by Len Bao 2 months, 1 week ago
Coverity noticed that assigning value -EINVAL to 'ret' in the if
statement is useless because 'ret' is overwritten a few lines later.
However, afer inspect the code, this warning reveals that we need to
return -EIVANL instead of the variable assignment. So, fix it.
