Subject: [PATCH 3/7] hid: egalax: Correct for device resolution report error (rev2)
Date: Mon, 29 Nov 2010 08:43:28 +0100	[thread overview]
Message-ID: <1291016612-25102-4-git-send-email-rydberg@euromail.se> (raw)
In-Reply-To: <1291016612-25102-1-git-send-email-rydberg@euromail.se>

The firmware of both supported devices report a X/Y maximum of 4095,
whereas in reality, it is eight times larger. Fixed with this patch.
