reset: intel: fix a compile warning about REG_OFFSET redefined
kernel test robot reports a compile warning about REG_OFFSET redefined in the reset-intel-gw.c after merging commite44ab4e14d
("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, from ./arch/arm/mach-ixp4xx/include/mach/io.h:15, from ./arch/arm/include/asm/io.h:198, from ./include/linux/io.h:13, from ./include/linux/iopoll.h:14, from ./include/linux/regmap.h:20, from drivers/reset/reset-intel-gw.c:12: ./arch/arm/mach-ixp4xx/include/mach/platform.h:25:0: note: this is the location of the previous definition #define REG_OFFSET 3 Reported-by: kernel test robot <lkp@intel.com> Fixes:c9aef213e3
