Summary
drm/i915/gt: Cleanup partial engine discovery failures
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/i915/gt: Cleanup partial engine discovery failures

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 destroypinnedcontext() helper for now. It's not really worth it with just a single callsite at the moment. (Janusz)
