Subject: [PATCH] driver: touchscreen: nvt_touch_f7a: do not report
ABS_MT_TOUCH_MAJOR/ABS_MT_WIDTH_MAJOR
It seems touchscreen chip can only report touch pressure from 0 to 255,
which should be ABS_MT_PRESSURE according to
https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt.
Do not set same values to ABS_MT_TOUCH_MAJOR/ABS_MT_WIDTH_MAJOR to avoid
breaking libinput and software.
Thanks @NotKit!
