Subject: [PATCH] powerpc/spufs: adjust list element pointer type

Other uses of &gang->aff_list_head, eg in spufs_assert_affinity, indicate
that the list elements have type spu_context, not spu as used here. Change
the type of tmp accordingly.

This has no impact on the execution, because tmp is not used in the body of
the loop.

Looks good to me; we could even use ctx there, rather than the separate
tmp variable.

I thought about that, but it seemed a little bit abusive, since ctx is
used in an iteration over another list. But if you prefer that I can
change it.
