[ Upstream commit 308646785e51976dea7e20d29a1842d14bf0b9bd ]
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)
