3.16.35-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Lucas Stach <l.stach@xxxxxxxxxxxxxx> commit a77c5422d7586003643377afdb9915e76d07d21c upstream. Remove the remnants of the workaround for erratum ERR005184 which was never completely implemented. The checks alone don't carry any value as we don't act properly on the result. A workaround should be added to the lane speed change in establish_link later.
