From c355bb1afc5fe59e559fff585204180a94c6d58c Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 10 Apr 2018 14:43:02 +0200 Subject: extcon: int3496: Use proper GPIO include Since commit eca0f13c836a ("extcon: int3496: Ignore incorrect IoRestriction for ID pin"), the driver doesn't use GPIOF_* flags anymore. We can thus now drop the deprecated include file for GPIO and use the new one.

When spinlock is locked for sending the notification, deadlock issue occured on the side of extcon consumer device. To fix this issue, extcon consumer device should always use the work. it is always not reasonable to use work. To fix this issue on extcon consumer device, release locking when sending the notification of connector state.
