Subject: [PATCH net-next] cxgb4: cleanup error code in setup_sge_queues_uld()

From: Dan Carpenter <[email-masked]>

The caller doesn't care about the error codes, they only check for zero
vs non-zero.  Still, it's better to preserve the negative error codes
from alloc_uld_rxqs() instead of changing it to 1.  We can also return
directly if there is a failure.

This isn't a bugfix so it should probably go to net-next, but the code
is pretty old.

The other error handling only checks the last iteration in the
for_each_port() loop.  I didn't change that because it's slightly
riskier and I can't test the code.
