[Intel-xe] [PATCH v5 2/3] drm/xe: Move defines before relevant fields

Francois Dugast francois.dugast at intel.com
Thu Jun 22 12:39:45 UTC 2023


Align on same rule in the whole file: defines then doc then relevant
field, with an empty line to separate fields.

v2:
  - Rebase on drm-xe-next
  - Fix ordering of defines and fields in uAPI (Lucas De Marchi)
v3: Remove useless empty lines (Lucas De Marchi)
v4: Move changelog to commit
v5: Rebase
