[Mesa-dev] [PATCH v15 02/16] i965/miptree: Add a helper function for image creation

[Daniel Stone]

From: Ben Widawsky <ben at bwidawsk.net>

This provides a common function or creating miptrees when there is an
existing DRIimage to use. That provides an easy way to add CCS
allocation.

v2: Make the new function assume there are always no layout flags. This
will be adjusted later.
