Revert "Input: synaptics-rmi4 - avoid processing unknown IRQs"
This reverts commit 7b9f7a928255a232012be55cb95db30e963b83a7.
That change should have had a fixes tag for
commit 24d28e4f1271 ("Input: synaptics-rmi4 - convert irq distribution to
irq_domain"). The conversion to irq_domain introduced the issue being
fixed by this commit.
In older kernels the bitmap IRQ accounting is done differently, and
it doesn't suffer from the same issue of calling handle_nested_irq(0).
Keeping this commit on kernels 4.14 and older causes problems with
touchpads due to the different semantics of the IRQ bitmasks.
