Subject: r600g: cleanup r600_transfer_struct
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=897af1d499ed91ed3629432424eb1ac62bff2c5f;p=mesa.git

r600g: cleanup r600_transfer_struct

Especially rename staging_texture to staging and change its type
to r600_resource. I will reuse it for buffers later.
