Input: xpad - use proper endpoint type

2014-12-06T23:55:37Z

commit a1f9a4072655843fc03186acbad65990cc05dd2d upstream. The xpad wireless endpoint is not a bulk endpoint on my devices, but rather an interrupt one, so the USB core complains when it is submitted. I'm guessing that the author really did mean that this should be an interrupt urb, but as there are a zillion different xpad devices out there, let's cover out bases and handle both bulk and interrupt endpoints just as easily.

Input: synaptics - adjust min/max on Thinkpad E540

2014-12-06T23:55:37Z

commit bce4f9e764c36bc35dd5c9cf9e057c09f422397d upstream. The LEN2006 Synaptics touchpad (as found in Thinkpad E540) returns wrong min max values. touchpad-edge-detector output: > Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event6 > Move one finger around the touchpad to detect the actual edges > Kernel says: x [1472..5674], y [1408..4684] > Touchpad sends: x [1264..5675], y [1171..4688] Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=88211 Signed-off-by: Binyamin Sagal Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: alps - ignore bad data on Dell Latitudes E6440 and E7440

2014-11-21T17:23:03Z

commit a7ef82aee91f26da79b981b9f5bca43b8817d3e4 upstream. Sometimes on Dell Latitude laptops psmouse/alps driver receive invalid ALPS protocol V3 packets with bit7 set in last byte. More often it can be reproduced on Dell Latitude E6440 or E7440 with closed lid and pushing cover above touchpad. If bit7 in last packet byte is set then it is not valid ALPS packet. I was told that ALPS devices never send these packets. It is not know yet who send those packets, it could be Dell EC, bug in BIOS and also bug in touchpad firmware... With this patch alps driver does not process those invalid packets, but instead of reporting PSMOUSE_BAD_DATA, getting into out of sync state, getting back in sync with the next byte and spam dmesg we return PSMOUSE_FULL_PACKET. If driver is truly out of sync we'll fail the checks on the next byte and report PSMOUSE_BAD_DATA then.

Input: alps - allow up to 2 invalid packets without resetting device

2014-11-21T17:23:03Z

commit 9d720b34c0a432639252f63012e18b0507f5b432 upstream. On some Dell Latitude laptops ALPS device or Dell EC send one invalid byte in 6 bytes ALPS packet. In this case psmouse driver enter out of sync state. It looks like that all other bytes in packets are valid and also device working properly. So there is no need to do full device reset, just need to wait for byte which match condition for first byte (start of packet). Because ALPS packets are bigger (6 or 8 bytes) default limit is small. This patch increase number of invalid bytes to size of 2 ALPS packets which psmouse driver can drop before do full reset. Resetting ALPS devices take some time and when doing reset on some Dell laptops touchpad, trackstick and also keyboard do not respond. So it is better to do it only if really necessary.

Input: alps - ignore potential bare packets when device is out of sync

2014-11-21T17:23:03Z

commit 4ab8f7f320f91f279c3f06a9795cfea5c972888a upstream. 5th and 6th byte of ALPS trackstick V3 protocol match condition for first byte of PS/2 3 bytes packet. When driver enters out of sync state and ALPS trackstick is sending data then driver match 5th, 6th and next 1st bytes as PS/2. It basically means if user is using trackstick when driver is in out of sync state driver will never resync. Processing these bytes as 3 bytes PS/2 data cause total mess (random cursor movements, random clicks) and make trackstick unusable until psmouse driver decide to do full device reset. Lot of users reported problems with ALPS devices on Dell Latitude E6440, E6540 and E7440 laptops. ALPS device or Dell EC for unknown reason send some invalid ALPS PS/2 bytes which cause driver out of sync. It looks like that i8042 and psmouse/alps driver always receive group of 6 bytes packets so there are no missing bytes and no bytes were inserted between valid ones. This patch does not fix root of problem with ALPS devices found in Dell Latitude laptops but it does not allow to process some (invalid) subsequence of 6 bytes ALPS packets as 3 bytes PS/2 when driver is out of sync. So with this patch trackstick input device does not report bogus data when also driver is out of sync, so trackstick should be usable on those machines.

Input: synaptics - add min/max quirk for Lenovo T440s

2014-11-21T17:23:03Z

commit e4742b1e786ca386e88e6cfb2801e14e15e365cd upstream. The new Lenovo T440s laptop has a different PnP ID "LEN0039", and it needs the similar min/max quirk to make its clickpad working.

commit d2682118f4bb3ceb835f91c1a694407a31bb7378 upstream. The sys_vendor / product_name are somewhat generic unfortunately, so this may lead to some false positives. But nomux usually does no harm, where as not having it clearly is causing problems on the Avatar AVIU-145A6. https://bugzilla.kernel.org/show_bug.cgi?id=77391 Reported-by: Hugo P Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman
