Subject: regulator: s5m8767: Remove regulator_dev pointer from state container
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e80fb721cac4202253939451678c873a222be2fa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

regulator: s5m8767: Remove regulator_dev pointer from state container

Don't store pointer to regulator_dev returned by
devm_regulator_register() in state container. It isn't used anywhere
outside of probe.
