Subject: [PATCH AUTOSEL 4.19 12/19] Input: elan_i2c - only increment wakeup count on touch
Date: Mon, 20 Jul 2020 17:38:43 -0400 [thread overview]
Message-ID: <20200720213851.407715-12-sashal@kernel.org> (raw)
In-Reply-To: <20200720213851.407715-1-sashal@kernel.org>
From: Derek Basehore <dbasehore@chromium.org>
[ Upstream commit 966334dfc472bdfa67bed864842943b19755d192 ]
This moves the wakeup increment for elan devices to the touch report.
This prevents the drivers from incorrectly reporting a wakeup when the
resume callback resets then device, which causes an interrupt to
occur.
