Subject: [PATCH] xwayland/shm: Use `calloc()`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, Xwayland pixmap SHM code uses `malloc()` to allocate the
xwl_pixmap.

Use `calloc()` instead, as the EGLstream backend does, as it is safer
(initializing the allocated data to 0).
