Subject: i965: Remove early release of DRI2 miptree
|
|
References: bfo#86281 bko#349519
|
|
|
|
intel_update_winsys_renderbuffer_miptree() will release the existing
|
|
miptree when wrapping a new DRI2 buffer, so we can remove the early
|
|
release and so prevent a NULL mt dereference should importing the new
|
|
DRI2 name fail for any reason. (Reusing the old DRI2 name will result
|
|
in the rendering going astray, to a stale buffer, and not shown on the
|
|
screen, but it allows us to issue a warning and not crash much later in
|
|
innocent code.)
