The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

 "A last minute fix for a regression introduced in the v6.5 merge
  window.

  The conversion of the software based interrupt resend mechanism to
  hlist missed to add a check whether the descriptor is already enqueued
  and dropped the interrupt descriptor lookup for nested interrupts.

  The missing check whether the descriptor is already queued causes
  hlist corruption and can be observed in the wild. The dropped parent
  descriptor lookup has not yet caused problems, but it would result in
  stale interrupt line in the worst case.

  Add the missing enqueued check and bring the descriptor lookup back to
  cure this"

  LoongArch: Remove redundant "source drivers/firmware/Kconfig"

The switch to using hlist for managing software resend of interrupts
broke resend in at least two ways:

First, unconditionally adding interrupt descriptors to the resend list can
corrupt the list when the descriptor in question has already been
added. This causes the resend tasklet to loop indefinitely with interrupts
disabled as was recently reported with the Lenovo ThinkPad X13s after
threaded NAPI was disabled in the ath11k WiFi driver.

This bug is easily fixed by restoring the old semantics of irq_sw_resend()
so that it can be called also for descriptors that have already been marked
for resend.

Second, the offending commit also broke software resend of nested
interrupts by simply discarding the code that made sure that such
interrupts are retriggered using the parent interrupt.

Add back the corresponding code that adds the parent descriptor to the
resend list.

Fixes: bc06a9e0 ("genirq: Use hlist for managing resend handlers")
