[patch V2 08/40] genirq/irqdomain: Remove the param count restriction from select()

From: Thomas Gleixner
Date: Mon Nov 21 2022 - 09:48:59 EST


Now that the GIC-v3 callback can handle invocation with a fwspec parameter
count of 0 lift the restriction in the core code and invoke select()
unconditionally when the domain provides it.

Preparatory change for per device MSI domains.
