dmaengine: dw-axi-dmac: do not print NULL LLI during error

Browse source

[ Upstream commit 86cb0defe0 ]

During debugging we have seen an issue where axi_chan_dump_lli()
is passed a NULL LLI pointer which ends up causing an OOPS due
to trying to get fields from it. Simply print NULL LLI and exit
to avoid this.
