From 68be7a5f281d50ee6572c8475ac6f1f99e0b1d1a Mon Sep 17 00:00:00 2001 From: Bruce Chen Date: Thu, 3 Mar 2022 15:36:03 +0800 Subject: extcon: usb-gpio: Remove disable irq operation in system sleep If disable vbus/id irq, it will lead to wakeup system fail in unisoc platform. In unisoc platform, Irq enable and irq wakeup are the same interrupt line. So remove disable vbus/id irq operation is a way to solve the issue.
