4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuval Shaia <yuval.shaia@xxxxxxxxxx>
[ Upstream commit ac6dbf7fa4707c75a247b540cc0b5c881f3d0ba8 ]
If one port fails to initialize an error message should indicate the
reason and driver should continue serving the working port(s) and other
HCA(s).
Fixes: e4b2d06892c7 ("IB/ipoib: Remove device when one port fails to init").
