Hi Bjorn,

There seem to be some error while applying the patch "arm64: dts:
qcom: sm8250: Disable the not yet supported cluster idle state".
This patch is already applied in your arm64-fixes-for-6.1 tree
(commit: cadaa773bcf161184fa428180516bae33a7bc667)

The new commit: 5c7fa5de12a31c1425cc87ba2ef27e6ae0a1788c,
however, disables the Big cpu idle state instead. I'm not sure if that
is intentional though.

Regards,
Amit Pundir
