[PATCH] regmap: fix compilation warning

From: Mike Rapoport
Date: Wed Sep 02 2015 - 07:08:17 EST


Explicitly initialize ret to -EINVAL in regmap_raw_read to fix the
following compilation warning:

CC drivers/base/regmap/regmap.o
linux/drivers/base/regmap/regmap.c: In function âregmap_raw_readâ:
linux/drivers/base/regmap/regmap.c:2174:6: warning: âretâ may be used uninitialized in this function [-Wmaybe-uninitialized]
int ret, i;
^
