Input: applespi - don't wait for responses to commands indefinitely.

2021-03-17T16:03:44+00:00

[ Upstream commit 0ce1ac23149c6da939a5926c098c270c58c317a0 ] The response to a command may never arrive or it may be corrupted (and hence dropped) for some reason. While exceedingly rare, when it did happen it blocked all further commands. One way to fix this was to do a suspend/resume. However, recovering automatically seems like a nicer option. Hence this puts a time limit (1 sec) on how long we're willing to wait for a response, after which we assume it got lost.

Input: elantech - fix protocol errors for some trackpoints in SMBus mode

2021-03-07T11:20:41+00:00

commit e4c9062717feda88900b566463228d1c4910af6d upstream. There are some version of Elan trackpads that send incorrect data when in SMbus mode, unless they are switched to use 0x5f reports instead of standard 0x5e. This patch implements querying device to retrieve chips identifying data, and switching it, when needed to the alternative report.

Input: i8042 - add ASUS Zenbook Flip to noselftest list

2021-03-04T09:26:41+00:00

commit b5d6e7ab7fe7d186878142e9fc1a05e4c3b65eb9 upstream. After commit 77b425399f6d ("Input: i8042 - use chassis info to skip selftest on Asus laptops"), all modern Asus laptops have the i8042 selftest disabled. It has done by using chassys type "10" (laptop). The Asus Zenbook Flip suffers from similar suspend/resume issues, but it _sometimes_ work and sometimes it doesn't. Setting noselftest makes it work reliably. In this case, we need to add chassis type "31" (convertible) in order to avoid selftest in this device.

Input: joydev - prevent potential read overflow in ioctl

2021-03-04T09:26:41+00:00

commit 182d679b2298d62bf42bb14b12a8067b8e17b617 upstream. The problem here is that "len" might be less than "joydev->nabs" so the loops which verfy abspam[i] and keypam[] might read beyond the buffer.
