3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rolf Eike Beer <redacted> 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.
