Subject: [PATCH] FROMLIST: i965: setup sized internalformat for
 MESA_FORMAT_R10G10B10A2_UNORM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit d2b60e433e5 introduced restrictions (as per GLES spec) on the
internal format. We need to setup a sized format for the texture image
so framebuffers created with that are considered complete.

This change fixes following Android CTS test in AHardwareBufferNativeTests
category:

   SingleLayer_ColorTest_GpuColorOutputAndSampledImage_R10G10B10A2_UNORM

(cherry picked from commit 412badd059de6f55cbcab10a55d052986a74b4cd)
