[Mesa-dev] [PATCH 11/30] i965/miptree: Add a return for updating of winsys

[Jason Ekstrand]

From: Ben Widawsky <ben at bwidawsk.net>

There is nothing particularly useful to do currently if the update
fails, but there is no point carrying on either. As a result, this has a
behavior change.

v2: Make the return type a bool (Topi)

v3: Don't leak the bo if update_winsys_renderbuffer fails. (Jason)
