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

Commit Message

Thomas Gleixner Nov. 21, 2022, 2:39 p.m. UTC

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.
