In this case the fourth argument is superfluous as it's always 0 or equal to the mask argument. This series proposes to add simple bit operations for setting, clearing and testing specific bits with regmap. The second patch uses all three in a driver that got recently picked into the net-next tree. The patches obviously target different trees so - if you're ok with the change itself - I propose you pick the first one into your regmap tree for v5.8 and then I'll resend the second patch to add the first user for these macros for v5.9. v1 -> v2: - convert the new macros to static inline functions Bartosz Golaszewski (2): regmap: provide helpers for simple bit operations net: ethernet: mtk-star-emac: use regmap bitops drivers/base/regmap/regmap.c | 22 +++++ drivers/net/ethernet/mediatek/mtk_star_emac.c | 80 ++++++++----------- include/linux/regmap.h | 36 +++++++++ 3 files changed, 93 insertions(+), 45 deletions(-) -- 2.26.1
