IB/ipoib: Fix CONFIG_INFINIBAND_IPOIB_CM If the above is turned off then ipoib_cm_dev_init unconditionally returns ENOSYS, and the newly added error handling in 0b3957 prevents ipoib from coming up at all: kernel: mlx4_0: ipoib_transport_dev_init failed kernel: mlx4_0: failed to initialize port 1 (ret = -12) Fixes: 0b39578bcde4 (IB/ipoib: Use dedicated workqueues per interface) Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
