HDMI plugout calls runtime suspend, which clears interrupt registers

Hello Viswanath,
A dot should be in the end of sentence, please. And should be better to
s/plugin/plug-in/ in the commit's message/title because 'plugin' sounds
as a noun.
[VL] Yes, I'll make the above changes.
Please don't version patch as v2 if v1 wasn't ever sent out.
[VL] Now that I have sent v2, shall I continue with v2 for the next
patch? Apologies for this oversight.
You should add a stable tag here to get patch backported into stable
kernel versions:
Cc: <[email protected]>
[VL] Yes, will add.
Signed-off-by: Viswanath L <[email protected]>
The kernel upstreaming rules require a full name. I'm pretty sure that L
isn't yours surname.
[VL] My name appears as "Viswanath L" in all company records and email
lists. I would strongly prefer to keep it this way, unless that is an
absolute no-no.
