Dmitry Osipenko ff2acd58e3 dmaengine: tegra-apb: Prevent race conditions on channel's freeing ... [ Upstream commit 8e84172e372bdca20c305d92d51d33640d2da431 ] It's incorrect to check the channel's "busy" state without taking a lock. That shouldn't cause any real troubles, nevertheless it's always better not to have any race conditions in the code.
