up to: 792ea6a074ae: genirq: Remove WARN_ON_ONCE() in generic_handle_domain_irq()
A single fix for a recent (introduced in 5.16) regression in the core
interrupt code. The consolidation of the interrupt handler invocation code
added an unconditional warning when generic_handle_domain_irq() is invoked
from outside hard interrupt context. That's overbroad as the requirement
for invoking these handlers in hard interrupt context is only required for
certain interrupt types. The subsequently called code already contains a
warning which triggers conditionally for interrupt chips which indicate
this requirement in their properties. Remove the overbroad one.
Thanks,
tglx
P.S.: I added a couple of links this time which point to relevant
context. If that's too broad, holler.
