From fb3c09ba20fff0fb7c5a6bcb2091dc62b6cce5e0 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Wed, 3 Apr 2019 15:15:44 -0700 Subject: Input: snvs_pwrkey - use dev_pm_set_wake_irq() to simplify code With calling dev_pm_set_wake_irq() to set SNVS ON/OFF button as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the enable_irq_wake()/disable_irq_wake() can be removed in suspend/resume callback, it simplifies the code.
