Subject: [PATCH] HID: fix A4Tech horizontal scrolling
Date:   Thu,  2 May 2019 23:36:39 +0200

Since recent high resolution scrolling changes the A4Tech driver must
check for the "REL_WHEEL_HI_RES" usage code.

Fixes: 2dc702c991e3774af9d7ce410eef410ca9e2357e (HID: input: use the
Resolution Multiplier for high-resolution scrolling)
