Subject: regulator: s5m8767: Convert to use regulator_[enable|disable|is_enabled]_regmap
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9c4c60554acfd6e32fe933cef43b2c16e65f1e4f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

regulator: s5m8767: Convert to use regulator_[enable|disable|is_enabled]_regmap

Since commit ca5d1b3524b4d
"regulator: helpers: Modify helpers enabling multi-bit control",
we can set enable_val setting for device that use multiple bits for control.
