Not in this patch because it leads to warning:

drivers/regulator/s5m8767.c: In function âs5m8767_reg_disableâ:
drivers/regulator/s5m8767.c:259:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]
drivers/regulator/s5m8767.c:253:6: warning: unused variable âmaskâ [-Wunused-variable]

I plan to remove the sec_reg_*() helpers because they are confusing
and error-prone (mixing u8 and unsigned int). After using standard regmap
API this "mask" variable could be removed.

Best regards,
Krzysztof
