Subject: regulator: wm831x: Convert to regulator_list_voltage_linear()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d31e954e07c838f44183addeecc7115d25e83266;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

regulator: wm831x: Convert to regulator_list_voltage_linear()

Only the alive LDOs can actually use this as all the other regulators have
two linear ranges.
