Thomas Gleixner 3fa53ec2ed pinctrl: samsung: Remove bogus irq_[un]mask from resource management 
The irq chip callbacks irq_request/release_resources() have absolutely no
business with masking and unmasking the irq.

The core code unmasks the interrupt after complete setup and masks it
before invoking irq_release_resources().

The unmask is actually harmful as it happens before the interrupt is
completely initialized in __setup_irq().

Remove it.
