[PATCH 00/11] Fix error paths in driver load

[Matthew Brost]

Combine a few series [1] [2] [3] plus some new patches to get driver
into working state.

The below test case passed on TGL:
for i in {1..19}; do echo "Run $i"; modprobe xe inject_driver_load_error=$i; rmmod xe; done

More error injection points should be added, likely 100s more. Posted to
likely hand off this work to a team member in a working state.
