[PATCH 3/3] Input: wm831x-ts - Move BTN_TOUCH reporting to data transfer

[Mark Brown <broonie@opensource.wolfsonmicro.com>]

Don't report BTN_TOUCH until we've got data as some less robust applications
can be confused by getting a touch event by itself and it doesn't seem
unreasonable for them to expect coordinates along with a touch.
