Subject: [PATCH] xtensa: fix memscan
Date: Sun, 22 Jan 2012 21:58:29 +0900 [thread overview]
Message-ID: <1327237109-25284-1-git-send-email-akinobu.mita@gmail.com> (raw)
Define memscan as memchr is wrong. Because the return value of memscan
and memchr are different when the character is not found.
So use generic memscan implementation to fix it.
