Pull irq fix from Thomas Gleixner:
"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"
