Not in this patch because it leads to warning:

drivers/regulator/s5m8767.c: In function ?s5m8767_reg_disable?:
drivers/regulator/s5m8767.c:259:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]
drivers/regulator/s5m8767.c:253:6: warning: unused variable ?mask? [-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

Not in this patch because it leads to warning:

drivers/regulator/s5m8767.c: In function ‘s5m8767_reg_disable’:
drivers/regulator/s5m8767.c:259:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]
drivers/regulator/s5m8767.c:253:6: warning: unused variable ‘mask’ [-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.
