maybe
	xe_tile *tile = gt_to_tile(gt);
	struct xe_tile_sriov_vf_selfconfig *config = tile->sriov.vf.self_config;

to avoid line split

> +	struct xe_ggtt *ggtt = gt_to_tile(gt)->mem.ggtt;

then
	struct xe_ggtt *ggtt = tile->mem.ggtt;

hmm, the real fix should be that GGTT lock is initialized right after GGTT was allocated
it looks that just split between GGTT alloc() and __init_early() was not ideal

note that while almost similar pattern was done for tile, in xe_tile_init_early() the pcode mutex is initialized

alternatively we can change VF to do not perform full query when doing early bootstrap as it is looking just for the GMDID

then we could use

	guard(mutex)(&ggtt->lock)

maybe "recovery" is not needed:

	if (!err && shift && shift != start)

hmm, the question is: why GGTT query can't be done under lock even without 'recovery' ?

what about naming style to use _locked suffix in function name if it expects to be already protected ?
