Subjectsound/soc/codecs/wm9081.c compiler warning
From
Date
I am getting this compiler warning in linus tree:

CC [M] sound/soc/codecs/wm9081.o
sound/soc/codecs/wm9081.c: In function ‘configure_clock’:
sound/soc/codecs/wm9081.c:674: warning: ‘new_sysclk’ may be used uninitialized in this function

This fixes the warning in my case, hope this will be helpful :
