Subject: [PATCH] Input: tsc40 - remove wrong announcement of pressure support
X-Extended-Stable: 3.5

commit 32ed1911fc79908d704023317d4ddeb3883fd07e upstream.

The tsc40 driver announces it supports the pressure event, but will never
send one. The announcement will cause tslib to wait for such events and
sending all touch events with a pressure of 0. Removing the announcement
will make tslib fall back to emulating the pressure on touch events so
everything works as expected.
