platform/x86: intel-vbtn: Fix missing tablet-mode-switch events
[ Upstream commit
14c200b7ca46b9a9f4af9e81d258a58274320b6f ]
2 issues have been reported on the Dell Inspiron 7352:
1. Sometimes the tablet-mode-switch stops reporting tablet-mode
change events.
Add a "VBDL" call to notify_handler() to work around this.
2. Sometimes the tablet-mode is incorrect after suspend/resume
Add a detect_tablet_mode() to resume() to fix this.
