Darrick J. Wong 423f7cf467 [SCSI] libsas: Don't BUG when connecting two expanders via wide port ... libsas: Don't BUG when connecting two expanders via wide port When a device is connected to an expander, the discovery process goes through sas_ex_discover_dev to figure out what's attached to the phy. If it is the case that the phy being discovered happens to be the second phy of a wide link to an expander, that discover_dev function will incorrectly call sas_ex_discover_expander, which creates another sas_port and tries to attach the other sas_phys to the new port, thus triggering a BUG. The correct thing to do is to check the other ex_phys of the expander to see if there's a sas_port for this sas_phy, and attach the sas_phy to the existing sas_port. This is easily triggered if one enables the phys of a wide port between expanders one by one. This second version of the patch fixes a small regression in the case where all the phys show up at once and we accidentally try to attach to a port that hasn't been created yet.
