Subject: mesa: add compressed_tex_sub_image() helper
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cb5627cbac2c68b0faccdedaeb462fbd507ddc7e;p=mesa.git

mesa: add compressed_tex_sub_image() helper

This reduces duplication between the dsa and non-dsa function
and will also be used in the following commit to add
KHR_no_error support.
