Subject: i965/drm: Unwrap the unnecessary drm_bacon_reloc_target_info struct.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b666654201d893072ca9aad48739d9cbbc537924;p=mesa.git

i965/drm: Unwrap the unnecessary drm_bacon_reloc_target_info struct.

This used to have another field, but now it's just a BO pointer.
