[PATCH 0/3] dmaengine: dw-axi-dmac: Fix LLP search, error reporting, and error dump

[Roland Dreier via B4 Relay]

One patch that build's on Jia Wang's fix for error-path LLI dump: the
same bug is present in axi_chan_block_xfer_complete(), although it's
not clear that it could ever be hit in practice, because the llp being
searched for should always be found.

Then two fixes for failed transfer handling: one to report status in
tx_result so that clients can know when a transfer hit an error, and
another to make log messages more informative than "Bad descriptor
submitted".
