[PATCH 0/3] DLN2 fixes related to suspend/resume

[Octavian Purdila <octavian.purdila@xxxxxxxxx>]

First patch in the series fixes a GPIO IRQ issues found during
suspend/resume testing, the next simplifies a bit the IRQ code and the
last adds support for suspend/resume to DLN2 to avoid a crash during
suspend caused by the fact that we cant unplug a GPIO controller while
it is in use.

As suggested by Johan, I have tested the suspend/resume on barebone
hardware, in addition to KVM USB pass-through and reset_resume routine
is not neccessary on barebone hardware. 

It looks like with KVM USB pass-through the emulated port is reseted
during suspend/resume regardless of the state of the physical port.

Octavian Purdila (3):
  gpio: dln2: fix issue when an IRQ is unmasked then enabled
  gpio: dln2: use bus_sync_unlock instead of scheduling work
  mfd: dln2: add suspend/resume functionality
