drm/i915/gt: Drop i915_address_space::file (v2)
There's a big comment saying how useful it is but no one is using this
for anything anymore.
It was added in
2bfa996e031b ("drm/i915: Store owning file on the
i915_address_space") and used for debugfs at the time as well as telling
the difference between the global GTT and a PPGTT. In
f6e8aa387171
("drm/i915: Report the number of closed vma held by each context in
debugfs") we removed one use of it by switching to a context walk and
comparing with the VM in the context. Finally, VM stats for debugfs
were entirely nuked in
db80a1294c23 ("drm/i915/gem: Remove per-client
stats from debugfs/i915_gem_objects")
v2 (Daniel Vetter):
- Delete a struct drm_i915_file_private pre-declaration
- Add a comment to the commit message about history
