Subject: Get the XIDeviceInfo instead of just the id.
X-Git-Url: https://diplodocus.org/git/xorg-xinput/commitdiff_plain/ff1b12265de1010aa22011c5db829274a8a3dab1?ds=sidebyside;hp=-c

Get the XIDeviceInfo instead of just the id.

This way we leak the XIDeviceInfo array, but then again it doesn't matter
since we exit after the command anyway.
And with the XIDeviceInfo around, we can actually print the name and
whatnot.
