Subject: sound/soc/codecs/wm9081.c compiler warning
Date: Wed, 15 Jul 2009 12:00:34 +0530	[thread overview]
Message-ID: <1247639434.2437.14.camel@ht.satnam> (raw)

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 :
