That doesn't hurt.
OK, I've used just the latter patch (because I somehow believe the first
one lowers the probability of bad behavior), so let's see if kswapd
consumes CPU again. I don't have any test patter to
ch because I'm also making some modifications to
this driver. This patch makes sense; other drivers also simply return
ENOMEM. Tested on ARM, Armada 388; the "good" code path still obviously
works :).

I realize that I'm late to the party (a merge request has been sent), but I

Without "microchip," on the front, the driver will print "missing

If I cherry-pick the following two commits

"detected irqchip that is shared with multiple gpiochips: please fix the
driver."
Hence, move the irq_chip definition from being driver static into the
struct mcp23s08. So a unique irq_chip is used for each gpiochip
