[PATCH] ivi-shell: SEGV occurs when multi touch happens in transition

[Nobuhiko Tanibata]

of application launching. This is because cancel callback is mistakenly
set to weston_touch_grab_interface. To fix this issue, add a
callback, touch_move_workspace_grab_frame and set it to the
weston_touch_grab_interface like desktop-shell.
