To support sparse GPIO maps, pinctrl-msm client drivers can specify that a given GPIO has a pin count of zero. These GPIOs will be considered "hidden". Any attempt to claim the GPIO will fail, and they will not be listed in debugfs. During a kexec shutdown, machine_kexec_mask_interrupts() will attempt to disable all IRQs, even those that aren't enabled. This includes GPIOs that are unavailable (npins == 0), so add a check to the irq mask and unmask functions. Signed-off-by: Timur Tabi<timur@xxxxxxxxxxxxxx>
I'm waiting for Björn's review of the two remaining patches.
Björn, do you have time to review these patches? I'm hoping to get them into 4.14.
