The gpiochip_lock_as_irq call can fail and return an error, while the
irq_startup is not expected to fail (returns an unsigned int which is not
checked by irq core code).

irq_request/release_resources functions have been created to address this
problem.

Move gpiochip_lock/unlock_as_irq calls into
irq_request/release_resources functions to prevent using a gpio as an irq
if the gpiochip_lock_as_irq call failed.

Patch applied with all the ACKs.

Hi Linus,

As suggested earlier, do you think it can be scheduled for the 4.0-rc
phase as a "fix"?

OK argh had to rebase my tree to get the patch out of the devel
branch but what can I do.

Yours,
Linus Walleij
