Subject: [PATCH] thinkpad_acpi: Add TP_HKEY_EV_SCREEN_FLIP (0x60c0) for Lenovo ThinkPad Yoga 12
Date: Sat, 10 Oct 2015 11:41:47 -0700 [thread overview]
Message-ID: <c6aa1c8ded9833fe62619d00f459ae438b1e2f9c.1444502507.git.dvhart@linux.intel.com> (raw)
From: Darren Hart <dvhart@infradead.org>
thinkpad_acpi reports "unhandled HKEY event 0x60c0" when switching
between laptop and tent/tablet mode on the ThinkPad Yoga 12. This key is
reported by atkbd serio0 as e058 and e059.
Add TP_HKEY_EV_SCREEN_FLIP to the list of ignored events and silence the
warning.
Cleanup whitespace on preceeding line for TP_HKEY_EV_KEY_FN_ESC.
