When creating a image from a texture, the image's dri_format is
set to the first plane's format, and used to look up for the
fourcc. e.g. for FOURCC_NV12 texture, the dri_format is set to
__DRI_IMAGE_FORMAT_R8, we end up with a wrong entry in function
intel_lookup_fourcc():
{ __DRI_IMAGE_FOURCC_R8, __DRI_IMAGE_COMPONENTS_R, 1,
{ { 0, 0, 0, __DRI_IMAGE_FORMAT_R8, 1 }, } },
instead of the correct one:
{ __DRI_IMAGE_FOURCC_NV12, __DRI_IMAGE_COMPONENTS_Y_UV, 2,
{ { 0, 0, 0, __DRI_IMAGE_FORMAT_R8, 1 },
{ 1, 1, 1, __DRI_IMAGE_FORMAT_GR88, 2 } } },
as a result, a wrong fourcc __DRI_IMAGE_FOURCC_R8 was returned.
To fix this bug, the image inherits the texture's planar_format that
has the original fourcc; Upon querying, if planar_format is set,
return the saved fourcc; Otherwise fall back to the old way.
v3: add a bug description and "cc mesa-stable" tag (Jason)
remove redundant null pointer check (Tapani)
squash 2 patches into one (James)
v2: fall back to intel_lookup_fourcc() when planar_format is NULL
