From 38a38f5a36da9820680d413972cb733349400532 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 25 May 2024 21:38:53 +0200 Subject: [PATCH 1/7] Input: silead - Always support 10 fingers When support for Silead touchscreens was orginal added some touchscreens with older firmware versions only supported 5 fingers and this was made the default requiring the setting of a "silead,max-fingers=10" uint32 device-property for all touchscreen models which do support 10 fingers. There are very few models with the old 5 finger fw, so in practice the setting of the "silead,max-fingers=10" is boilerplate which needs to be copy and pasted to every touchscreen config. Reporting that 10 fingers are supported on devices which only support 5 fingers doesn't cause any problems for userspace in practice, since at max 4 finger gestures are supported anyways. Drop the max_fingers configuration and simply always assume 10 fingers.

This happens because match_attribute() blindly assumes that all entries in da_tokens have an associated entry in token_attrs. This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute(). Fix this by defining an extra struct for each pair of token attributes and use container_of() to retrieve token information. Tested on a Dell Inspiron 3050.
