2019-07-26Input: alps - fix a mismatch between a condition check and its commentHui Wang
commit 771a081e44a9baa1991ef011cc453ef425591740 upstream. In the function alps_is_cs19_trackpoint(), we check if the param[1] is in the 0x20~0x2f range, but the code we wrote for this checking is not correct: (param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f, it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f... Now fix it with a new condition checking ((param[1] & 0xf0) == 0x20).

commit 1976d7d200c5a32e72293a2ada36b7b7c9d6dd6e upstream. Adds the Lenovo T580 to the SMBus intertouch list for Synaptics touchpads. I've tested with this for a week now, and it seems a great improvement. It's also nice to have the complaint gone from dmesg.

2019-07-26Input: alps - don't handle ALPS cs19 trackpoint-only deviceHui Wang
commit 7e4935ccc3236751e5fe4bd6846f86e46bb2e427 upstream. On a latest Lenovo laptop, the trackpoint and 3 buttons below it don't work at all, when we move the trackpoint or press those 3 buttons, the kernel will print out: "Rejected trackstick packet from non DualPoint device" This device is identified as an alps touchpad but the packet has trackpoint format, so the alps.c drops the packet and prints out the message above. According to XiaoXiao's explanation, this device is named cs19 and is trackpoint-only device, its firmware is only for trackpoint, it is independent of touchpad and is a device completely different from DualPoint ones. To drive this device with mininal changes to the existing driver, we just let the alps driver not handle this device, then the trackpoint.c will be the driver of this device if the trackpoint driver is enabled. (if not, this device will fallback to a bare PS/2 device) With the trackpoint.c, this trackpoint and 3 buttons all work well, they have all features that the trackpoint should have, like scrolling-screen, drag-and-drop and frame-selection.

2019-07-21Input: synaptics - enable SMBUS on T480 thinkpad trackpadCole Rogers
commit abbe3acd7d72ab4633ade6bd24e8306b67e0add3 upstream. Thinkpad t480 laptops had some touchpad features disabled, resulting in the loss of pinch to activities in GNOME, on wayland, and other touch gestures being slower. This patch adds the touchpad of the t480 to the smbus_pnp_ids whitelist to enable the extra features. In my testing this does not break suspend (on fedora, with wayland, and GNOME, using the rc-6 kernel), while also fixing the feature on a T480.

2018-10-19Input: synaptics - avoid using uninitialized variable when probingDmitry Torokhov
synaptics_detect() does not check whether sending commands to the device succeeds and instead relies on getting unique data from the device. Let's make sure we seed entire buffer with zeroes to make sure we will not use garbage on stack that just happen to be 0x47.

2018-10-15Input: cyapa - mark expected switch fall-throughsGustavo A. R. Silva
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I replaced the "Fallthrough state" commern with a proper "Fall through", which is what GCC is expecting to find.

2018-08-01Input: elan_i2c_smbus - cast sizeof to int for comparisonJulia Lawall
Comparing an int to a size, which is unsigned, causes the int to become unsigned, giving the wrong result. i2c_smbus_read_block_data can return the result of i2c_smbus_xfer, whih can return a negative error code. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ int x; expression e,e1; identifier f; @@ *x = f(...); ... when != x = e1 when != if (x < 0 || ...) { ... return ...; } *x < sizeof(e) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

atp_open(), atp_recover() and atp_resume() are never called in atomic context. They call usb_submit_urb() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL.
