[PATCH] platform/surface: aggregator: Do not mark interrupt as shared

[PATCH] platform/surface: aggregator: Do not mark interrupt as shared

[Maximilian Luz]

Having both IRQF_NO_AUTOEN and IRQF_SHARED set causes
request_threaded_irq() to return with -EINVAL (see comment in flag
validation in that function). As the interrupt is currently not shared
between multiple devices, drop the IRQF_SHARED flag.

Fixes: 507cf5a2f1e2 ("platform/surface: aggregator: move to use request_irq by IRQF_NO_AUTOEN flag")

Thank you I'll pick this up (and at it to the pdx86/fixes branch too)
once 5.13-rc1 is out.

Regards,

Hans

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

I will also include this in the next pdx86-fixes pull-req for 5.13.

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

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
