2020-12-11Input: elantech - fix protocol errors for some trackpoints in SMBus modejingle.wu2-2/+101
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.

2020-12-09Input: cyapa - switch to using devm_add_action_or_reset()Fuqian Huang1-6/+4
devm_add_action_or_reset() is introduced as a helper function which internally calls devm_add_action(). If devm_add_action() fails then it will execute the action mentioned and return the error code. This reduce source code size (avoid writing the action twice) and reduce the likelyhood of bugs.

Newer controllers (identified as "pattern" version 2) send higher resolution reports, with 16-bit X and Y coordinates (previous generations used 12-bit values). These new high resolution reports use report ID of 0x60. SMbus controllers use the same buffer size for both the new and old reports, and because of that high resolution reports no longer carry area of contact data with SMbus.

This laptop (and perhaps other variants of the same model) reports an SMBus-capable Synaptics touchpad. Everything (including suspend and resume) works fine when RMI is enabled via the kernel command line, so let's add it to the whitelist.

2020-02-14Input: cyapa - replace zero-length array with flexible-array memberGustavo A. R. Silva1-4/+4
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-02-13Input: synaptics - remove the LEN0049 dmi id from topbuttonpad listBenjamin Tissoires1-1/+1
The Yoga 11e is using LEN0049, but it doesn't have a trackstick. Thus, there is no need to create a software top buttons row. However, it seems that the device works under SMBus, so keep it as part of the smbus_pnp_ids.
