X-Git-Tag: v4.19~1637^2~264
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ac6dbf7fa4707c75a247b540cc0b5c881f3d0ba8;p=platform%2Fkernel%2Flinux-rpi.git

IB/ipoib: Warn when one port fails to initialize

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").
