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. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>
