From 3fa53ec2ed885b0aec3f0472e3b4a8a6f1cd748c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 29 Jun 2017 23:33:35 +0200 Subject: 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.
