Subject: [PATCH] clk: qcom: camcc-sc7180: Use runtime PM ops instead of clk ones
Date: Sat, 14 Nov 2020 09:44:08 -0800	[thread overview]
Message-ID: <20201114174408.579047-1-sboyd@kernel.org> (raw)

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.
