Commit Message

Chris Lesiak May 4, 2018, 1:20 p.m. UTC 
Fix incorrect logic in gpiochip_irqchip_add_key().
A driver needs to override both irq_request_resources and
irq_release_resources, otherwise gpiochip_irq_reqres and
gpiochip_irq_relres should be used.

Changed v1 -> v2:
  Correct repeated irq_request_resources in commit message
