[PATCH v6 weston 19/19] input: Don't test keyboard/pointer/touch pointers

Derek Foreman derekf at osg.samsung.com
Wed Jun 3 13:53:38 PDT 2015


Keyboards and pointers aren't freed when devices are removed, so we should
really be testing keyboard_device_count and pointer_device_count in most
cases, not the actual pointers. Otherwise we end up with different
behaviour after removing a device than we had before it was inserted.

This commit renames the touch/keyboard/pointer pointers and adds helper
functions to get them that hide this complexity and return NULL when
*_device_count is 0.
