Subject: [PATCH AUTOSEL 5.1 12/51] HID: a4tech: fix horizontal scrolling
Date: Tue, 25 Jun 2019 23:40:28 -0400 [thread overview]
Message-ID: <20190626034117.23247-12-sashal@kernel.org> (raw)
In-Reply-To: <20190626034117.23247-1-sashal@kernel.org>
From: Błażej Szczygieł <spaz16@wp.pl>
[ Upstream commit abf82e8f7e9af40a49e3d905187c662a43c96c8f ]
Since recent high resolution scrolling changes the A4Tech driver must
check for the "REL_WHEEL_HI_RES" usage code.
Link: https://bugzilla.kernel.org/show_bug.cgi?id=203369
Fixes: 2dc702c991e3774af9d7ce410eef410ca9e2357e ("HID: input: use the Resolution Multiplier for high-resolution scrolling")
