Subject: drm/xe/display: Add frontbuffer setter/getter for xe_bo
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cd494efdb8433f4a78f9bedb3e67d7505690f141;p=linux.git

drm/xe/display: Add frontbuffer setter/getter for xe_bo

Xe is not carrying frontbuffer pointer in xe_bo. Define it's getter as
NULL.  Setter simply returns pointer which was provided as a
parameter.

v3: Do not take any references
v2: Handle xe_bo_put as well
