From: Wei Yongjun <redacted>

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

Hi David,
Forgive me for acting late on this but just realized that this patch will
Conflict with Doug Ledford's hns-roce's HNS driver. This might lead to
problems later during this merge window of 4.9. RoCE base driver has already
suffered because of such problem during earlier merge window. 

Can I request you to drop this patch for now? We shall submit this patch later
again either through hns-roce or directly to net-next.

Thanks in anticipation
Salil
