commit c9bfb2f0031a2de664147ebbfb90f95bb12fdf79 upstream.
The commit 78bcac7b2ae1e ("Input: add support for the STMicroelectronics
FingerTip touchscreen) used the 'touchscreen_parse_properties()' helper
function in order to get the value of common properties.
But, commit 78bcac7b2ae1e didn't set the capability of ABS_MT_POSITION_*
before calling touchscreen_parse_properties(). In result, the max_x and
max_y of 'struct touchscreen_properties' were not set.

Input: stmfts - mark all PM functions as __maybe_unused2017-06-09T16:54:56+00:00Arnd Bergmannarnd@arndb.de2017-06-09T16:54:09+00:00urn:sha1:d4c9354b4015aa8d1b032c368682dd20a00f4e1f
We get a harmless warning when CONFIG_RUNTIME_PM is disabled:
drivers/input/touchscreen/stmfts.c:760:12: error: 'stmfts_runtime_resume' defined but not used [-Werror=unused-function]
static int stmfts_runtime_resume(struct device *dev)
drivers/input/touchscreen/stmfts.c:748:12: error: 'stmfts_runtime_suspend' defined but not used [-Werror=unused-function]
static int stmfts_runtime_suspend(struct device *dev)
The regular PM functions are already marked as __maybe_unused, so let's
do the same for the runtime-PM as well.

The stmfts (ST-Microelectronics FingerTip S) touchscreen device is a
capacitive multi-touch controller mainly for mobile use. It's connected
through i2c bus at the address 0x49 and it interfaces with userspace
through input event interface.
At the current state it provides a touchscreen multitouch functionality up
to 10 fingers. Each finger is enumerated with a distinctive id (from 0 to
9).
If enabled the device can support single "touch" hovering, by providing
three coordinates, x, y and distance.
It is possible to select the touchkey functionality which provides a basic
two keys interface for "home" and "back" menu, typical in mobile phones.
