Note that I left out the stable tag here as the offending patch was merged as a fix for 6.5 and I specifically assumed this fixup would go in as a fix for 6.5 as well. > Cc: Konrad Dybcio <konrad.dybcio@linaro.org> > Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Johan

Make sure to decrement the runtime PM usage count before returning in case RCG dynamic frequency switch initialisation fails.
