Lior Amsalem 42f77f15b1 dmaengine: mv_xor: bug fix for racing condition in descriptors cleanup ... commit 9136291f1dbc1d4d1cacd2840fb35f4f3ce16c46 upstream. This patch fixes a bug in the XOR driver where the cleanup function can be called and free descriptors that never been processed by the engine (which result in data errors). The cleanup function will free descriptors based on the ownership bit in the descriptors.
