We remove the calls to clk_pm_runtime_{get,put}() in this path > because they're superfluous now that we know the devices are runtime > resumed. This also squashes a bug where the return value of > clk_pm_runtime_get() wasn't checked, leading to an RPM count underflow > on error paths. > > Fixes: 1bb294a7981c ("clk: Enable/Disable runtime PM for clk_summary") > Cc: Taniya Das <quic_tdas@quicinc.com> > Cc: Douglas Anderson <dianders@chromium.org> > Signed-off-by: Stephen Boyd <sboyd@kernel.org> > ---
