Exactly, it's reasonable to replace this with the helper function.
I'll check and apply it.

Although I'm worried that the register have a value that is neither
enable_val or disable_val, the "is_enabled" function returns whether
the regulator is enabled or not, so I can apply regulator_is_enabled_regmap().
I'll apply it in v3.
Thank you,
