Input: synaptics - only report width on hardware that supports it
Synaptics devices report fixed value of 5 for finger/palm widths
on devices that do not support capability and driver further
hardcodes to 5. Stop reporting this fixed value when its not
supported since its not useful.
This will aid applications so they can better auto-enable support
for multi-touch emulation and palm detection logic using finger
width only for devices that support width detection.
I can find no applications that currently require existence on
ABS_TOOL_WIDTH. Since only synaptics and bcm input devices
currently support this tool, it seems they must handle it
gracefully.
