[PATCH] clk: qcom: camcc-sc7180: Use runtime PM ops instead of clk ones

From: Stephen Boyd
Date: Sat Nov 14 2020 - 12:44:32 EST


Let's call pm_runtime_get() here instead of calling the PM clk APIs
directly. This avoids a compilation problem on CONFIG_PM=n where the
pm_clk_runtime_{resume,suspend}() functions don't exist and covers the
intent, i.e. enable the clks for this device so we can program PLL
settings.
