José Expósito 806d4a1393 tablet: check libevdev_get_abs_info() return value
Commit b5f0536a4f ("quirks: add a quirk for the Wacom 524c device")
added the quirk "AttrEventCodeDisable=ABS_TILT_X;ABS_TILT_Y;" to the
Wacom 524c.

When using the pen in a display with tilt support, the tilt X/Y axes
are set as changed. Using the pen again, but this time in the display
without tilt support, will try to get the tilt information, crashing.

Check the return value of libevdev_get_abs_info() to avoid this crash.

libinput

libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.

libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.

User documentation

Documentation explaining features available in libinput is available here.

This includes the FAQ and the instructions on reporting bugs.
