From ddfe7e1ce3d5ce5ae0b25d107ba9d26fe8a4923b Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 10 Apr 2021 00:33:46 -0700 Subject: [PATCH] Input: cyttsp - set abs params for ABS_MT_TOUCH_MAJOR The driver is certainly reporting pressure in cyttsp_report_tchdata() with input_report_abs(input, ABS_MT_TOUCH_MAJOR, tch->z); so we should also advertise this capability.
