Subject: st/mesa: Fix glEGLImageTargetTexture2DOES.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0f74efdef05c5c27b3137163d795dc91f34cc114;p=mesa.git

st/mesa: Fix glEGLImageTargetTexture2DOES.

stObj->pt should be set in st_bind_surface, just as in st_TexImage.  On
the other hand, st_TexImage should unreference stObj->pt.  It also needs
to initialize the texture image again as _mesa_clear_texture_object
clears the image.
