swiotlb: clean up EXPORT_SYMBOL usage
Impact: cleanup swiotlb uses EXPORT_SYMBOL in an inconsistent way. Some functions use EXPORT_SYMBOL at the end of functions. Some use it at the end of swiotlb.c. This cleans up swiotlb to use EXPORT_SYMBOL in a consistent way (at the end of functions). Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>
