From 75b66d8ccd5772b00a7328c2cf75bc506ec532a1 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Wed, 7 Sep 2011 13:13:41 -0700 Subject: mtd: nand: switch `check_pattern()' to standard `memcmp()' A portion of the `check_pattern()' function is basically a `memcmp()'. Since it's possible for `memcmp()' to be optimized for a particular architecture, we should use it instead.
