[PATCH] Regmap: Add missing header

From: Mateusz Krawczuk
Date: Tue Aug 06 2013 - 12:35:10 EST

regmap.h requires linux/err.h if CONFIG_REGMAP is not defined. Without it I get
CC drivers/media/platform/exynos4-is/fimc-reg.o
In file included from drivers/media/platform/exynos4-is/fimc-reg.c:14:0:
include/linux/regmap.h: In function âregmap_writeâ:
include/linux/regmap.h:525:10: error: âEINVALâ undeclared (first use in this function)
include/linux/regmap.h:525:10: note: each undeclared identifier is reported only once for each function it appears in
