Subject: [PATCH] Input: cyttsp5 - fix sensing configuration data structure
Date:   Tue, 11 Apr 2023 23:16:51 +0200

Prior to this patch, the sensing configuration data was not parsed
correctly, breaking detection of max_tch. The vendor driver includes
this field. This change informs the driver about the correct maximum
number of simultaneous touch inputs.

Tested on a Pine64 PineNote with a modified touch screen controller
firmware.
