[Mesa-dev] [PATCH] i965: pass wanted format to intel_miptree_create_for_dri_image

[Tapani Pälli]

Change b3a44ae7a4 caused regressions on Android where DRI and renderbuffer
can disagree on the format being used. This patch removes the colorspace
parameter and instead we pass renderbuffer format. For non-winsys images we
still do srgb/linear modification in same manner as change b3a44ae7a4 wanted
but take format from renderbuffer instead of DRI image.

This patch fixes regressions seen with following test sets:

   dEQP-EGL.functional.color_clears*
   dEQP-EGL.functional.render*
