Subject: regulator: wm831x: Register all normal regulators
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b7ca87884b138f27f042dd32bd16e9a9f295da77;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

regulator: wm831x: Register all normal regulators

Register all normal regulators rather than skipping unconfigured ones now
that the core can handle regulators without init data. Skip the boost and
isink regulators since they are normally controlled by other drivers.
