What commit does this fix? Is it needed to go to stable kernel(s)?
That would be b3b708fa2780cd2b5d8266a8f0c3a1cab364d4d2 ("wake up from a
serial port").
I do not know of standard Linux distribution user-space relying on the
wake-up counts from sysfs, though I certainly do care.
The patch I submitted should backport fine all the way down to 4.14
where irqd_is_wakeup_set is available. Do you want me to submit a v2
with that Fixes tag?
