Hi, I reported a lockdep warning in the ZynqMP DMA driver a few weeks ago [0]. This series fixes the reported warning and performs some cleanup that I found while looking at the driver more closely. Patches 1-4 are the cleanups. They affect the log output of the driver, allow to compile the driver on other platforms when COMPILE_TEST is enabled, and remove unused included header files from the driver. Patches 5-7 aim to fix the lockdep warning. Patch 5 and 6 restructure the locking in the driver to make it more fine-grained instead of holding the lock for the entire tasklet. Patch 7 finally fixes the warning.
