--------------------------------

[ Upstream commit 1f65ea41 ]

Whenever the compose width/height values change, the dev->bitmap_cap
vmalloc'ed array must be freed and dev->bitmap_cap set to NULL.

This was done in some places, but not all. This is only an issue if
overlay support is enabled and the bitmap clipping is used.
