[PATCH v12 02/25] genirq/irqdomain: Remove the param count restriction from select()

From: Anup Patel
Date: Sat Jan 27 2024 - 11:19:24 EST


From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

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.
