Subject: [PATCH v6 0/4] scsi: libsas: Fix the failure of adding phy with zero-address to port
This series is to solve the problem of a BUG() when adding phy with zero
address to a new port.

1. rename sas_add_parent_port() to sas_ex_add_parent_port() based on
John's suggestion.
2. Distill port settings into a single patch.
3. Update comments information.
v4 -> v5
1. Add new helper sas_port_add_ex_phy() based on John's suggestion.
2. Move sas_add_parent_port() to sas_expander.c based on John's suggestion.
3. Update the comments.
v3 -> v4:
1. Update patch title and comments based on John's suggestion.
v2 -> v3:
1. Set ex_dev->parent_port to NULL when the number of PHYs of the parent
port becomes 0.
2. Update the comments.
v1 -> v2:
1. Set ex_phy->port with parent_port when ex_phy is added to the parent
port.
2. Set ex_phy to NULL when free expander.
3. Update the comments.
