The ili9322 driver has a volatile_reg() operation in it's regmap which always returns false. This is redundant since it is the default in the regmap core, remove the operation for a trivial code size and performance improvement.Signed-off-by: Mark Brown <broo...@kernel.org> --- drivers/gpu/drm/panel/panel-ilitek-ili9322.c | 6 ------ 1 file changed, 6 deletions(-) diff --git a/drivers/gpu/drm/panel/panel-ilitek-ili9322.c b/drivers/gpu/drm/panel/panel-ilitek-ili9322.c index 61c872f0f7ca..15b81e5228b5 100644 --- a/drivers/gpu/drm/panel/panel-ilitek-ili9322.c +++ b/drivers/gpu/drm/panel/panel-ilitek-ili9322.c @@ -325,11 +325,6 @@ static struct regmap_bus ili9322_regmap_bus = { .val_format_endian_default = REGMAP_ENDIAN_BIG, };-static bool ili9322_volatile_reg(struct device *dev, unsigned int reg)-{ - return false; -} - static bool ili9322_writeable_reg(struct device *dev, unsigned int reg) { /* Just register 0 is read-only */ @@ -343,7 +338,6 @@ static const struct regmap_config ili9322_regmap_config = { .val_bits = 8, .max_register = 0x44, .cache_type = REGCACHE_RBTREE, - .volatile_reg = ili9322_volatile_reg, .writeable_reg = ili9322_writeable_reg, };
