[meta-freescale] [PATCH v2 5/5] weston: Touch events cause startup failure

[Tom Hochstein]

Pressing the touch panel continously during boot up caused
weston to crash. The weston view was being accessed before it
was fully initialized, so now we guard against this.

Upstream-Status: Denied [Could not reproduce]
