Date: Mon, 5 Jan 2015 23:28:32 +0100 From: Gabriele Mazzotta <gabriele.mzt@...il.com> To: linux-input@...r.kernel.org Cc: dmitry.torokhov@...il.com, rydberg@...omail.se, linux-kernel@...r.kernel.org, silverhammermba@...il.com, peter.hutterer@...-t.net, hdegoede@...hat.com, benjamin.tissoires@...il.com, Gabriele Mazzotta <gabriele.mzt@...il.com> Subject: [PATCH v2 1/4] input: synaptics - fix pressure values calculation on image sensors The pressure values retrieved from secondary packets was incorrectly shifted, making them lower than what they actually were. Since this only happened with secondary packets, the values reported when only one finger was present on the touchpad were correct.
