Subject: r600: reset tex array override even when no view bound
X-Git-Tag: upstream/19.3.0~6733
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e2fecf57e343961cd1db9251cef2c9eb95948d2f;p=platform%2Fupstream%2Fmesa.git

r600: reset tex array override even when no view bound

If no view is bound we still should reset the override to 0
and array mode.

This should fix misrendering in firefox WebRender since
the pbo sampler was removed.

Fixes: 1250383e36 (st/mesa: remove sampler associated with buffer texture in pbo logic)
