Subject[PATCH v1] reset: intel: fix a compile warning about REG_OFFSET redefined
Date
kernel test robot reports a compile warning about REG_OFFSET redefined
in the reset-intel-gw.c after merging commit e44ab4e14d6f4 ("regmap:
Simplify implementation of the regmap_read_poll_timeout() macro"). the
warning is like that:

drivers/reset/reset-intel-gw.c:18:0: warning: "REG_OFFSET" redefined
#define REG_OFFSET GENMASK(31, 16)

In file included from ./arch/arm/mach-ixp4xx/include/mach/hardware.h:30:0,

#define REG_OFFSET 3
