Add a separate change that removes flags from the spin lock in the IRQ handler.

Exactly my point why I'm suggesting to have _separate_ change!
I am just splitting an
existing function into two, where one takes the lock and the other does
the work. Do you mean using a different locking function? I'm not
entirely sure what you're suggesting.
Yes, as a prerequisite

spin_lock_irqsave -> spin_lock().
