Subject: [ 077/147] mtd: autcpu12-nvram: Fix compile breakage

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexander Shiyan <shc_work@...l.ru>

commit d1f55c680e5d021e7066f4461dd678d42af18898 upstream.

Update driver autcpu12-nvram.c so it compiles; map_read32/map_write32
no longer exist in the kernel so the driver is totally broken.
Additionally, map_info name passed to simple_map_init is incorrect.
