Subject: [PATCH v1 1/1] swiotlb: remove unused field "used" from struct io_tlb_mem

From: Petr Tesarik <[email protected]>

Commit 20347fca71a3 ("swiotlb: split up the global swiotlb lock") moved
the number of used slots to struct io_tlb_area, but it did not remove
the field from struct io_tlb_mem.
