Linus Torvalds 92ea77275b Fix crash with irqpoll due to the IRQF_IRQPOLL flag testing
With irqpoll enabled, trying to test the IRQF_IRQPOLL flag in the
actions would cause a NULL pointer dereference if no action was
installed (for example, the driver might have been unloaded with
interrupts still pending).

So be a bit more careful about testing the flag by making sure to test
for that case.

(The actual _change_ is trivial, the patch is more than a one-liner
because I rewrote the testing to also be much more readable.

Original (discarded) bugfix by Bernhard Walle.
