[PATCH v2 5/6] thermal: brcmstb_thermal: Restructure interrupt registration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If we are successful grabbing the interrupt resource, then register an
interrupt handler, this makes it easier to support the interrupt as
being optional, which is it for 7216.
