'ret' is known to be 0 here.
The expected error code is stored in 'tx_pipe->dma_queue', so use it
instead.
While at it, switch from %d to %pe which is more user friendly.

Hi,
Apparently %pe is only supported up to (including) 5.5. It is not part
of 5.4.123.
So this patch should not be backported here or should be backported
differently, ie:
leave dev_err as-is
move "ret = PTR_ERR(tx_pipe->dma_queue);" 1 line above
(or %pe should be backported first)
PS: adding Dan Carpenter because we had a small discussion about some
potential backport issue when, using %pe
