drm/i915/gt: Cleanup partial engine discovery failures
Published Aug 21, 2024
5.5
MEDIUMCVSS 3.1
EPSS 0.25%
Description
If we abort driver initialisation in the middle of gt/engine discovery, some engines will be fully setup and some not. Those incompletely setup engines only have 'engine->release == NULL' and so will leak any of the common objects allocated.
v2: - Drop the destroy_pinned_context() helper for now. It's not really worth it with just a single callsite at the moment. (Janusz)
