I think for 5.4 the most expedient thing is to take these two:
a95881d6aa2c pinctrl: qcom: Properly clear "intr_ack_high" interrupts
when unmasking
4079d35fa4fc pinctrl: qcom: No need to read-modify-write the interrupt status
Then it should apply cleanly and you'll get this one fix.
After fixing, you might hit the next failure when trying to apply
("pinctrl: qcom: Don't clear pending interrupts when enabling"). That
one might be slightly harder to backport since it interacts with the
PDC patches. Presumably anyone running a real system on 5.4 also has
the PDC patches backported so they can get wakeup, but getting all the
PDC support in 5.4 stable would probably be too much of a "feature"
for linux-stable? In any case, my default answer for that I'd be
happy to help review a backport if someone saw a benefit but I won't
attempt it myself.
