[Intel-gfx] [PATCH v2 0/6] A collection of cleanups

[Dave Gordon]

Various things can go wrong during initialisation and teardown, but they
usually don't, so the error-handling paths go largely untested.  This
collection of patches fixes some things I recently noticed. Some might
lead to a kernel OOPS, but mostly they're leaks and other inconsistencies.

Includes Nick Hoath's patch to swap context/engine teardown, because
that helps make setup & teardown more consistent too.

v2:
    Patches reordered and the previous [1/4] split into [4..6/6],
    so that the bugs that it's fixing are more clearly visible
    (Mika Kuoppala, although he said it wasn't actually *necessary*).
