[PATCH v8 weston] input: Don't test keyboard/pointer/touch pointers
Derek Foreman
derekf at osg.samsung.com
Fri Jul 31 14:55:32 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.
Reviewed-by: Jonas Ådahl <jadahl at gmail.com>
Signed-off-by: Derek Foreman <derekf at osg.samsung.com>
---
Removed an accidentally added newline
Added comments to the 3 functions that use *_state pointers
directly explaining why we're doing out of spec things to
avoid a race.
rebased (and fixed exposay and zoom conflicts)
