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"
