+ [ Test Plan ]
+ * Normal certification and kernel regression testing will be run on all GM'd
+ platforms. The failure was catestrophic and was easily caught.
+
+ [ Where problems could occur ]
+ * Xilinx has changes to the dmaengine driver that have not been upstreamed,:
+ specifically adding support for cyclic dma mode. There is a risk that these
+ non-upstreamed changes have not been tested with this change.
+
+ [ Other Info ]
+ * BugLink: https://bugs.launchpad.net/bugs/2072456
+ * Upstream state in original commit was incorrect.
+ * Upstream commit "dma: xilinx_dpdma: Fix locking"
