Subject: [PATCH] platform/x86: hp-wmi: Ignore Smart Experience App event

Sometimes hp-wmi driver complains on system resume:
[ 483.116451] hp_wmi: Unknown event_id - 33 - 0x0

According to HP it's a feature called "HP Smart Experience App" and it's
safe to be ignored.

Jorge,

Can you please review KH's submission?

Also to avoid playing wack-a-mole, can you cross reference your internal
specs against any other missing event IDs and send follow up patches if
anything else is missing?

Thanks,

Thank you for your patch, I've applied this patch to my fixes
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=fixes

Note it will show up in my fixes branch once I've pushed my
local branch there, which might take a while.

I will include this patch in my next fixes pull-req to Linus
for the current kernel development cycle.

Regards,

Hans
