commit b9e63d6c7c0e94a99e1af7c9c0c7fad13a2f2453 upstream.
A sanity check on phy_mask was added in commit 3668651def ("scsi:
mpi3mr: Sanitise num_phys"). This causes warning messages when more than
64 phys are detected and devices connected to phys greater than 64 are
dropped.
The phy_mask bitmap is only needed for controller phys and not required
for expander phys. Controller phys can go up to a maximum of 64 and
therefore u64 is good enough to contain phy_mask bitmap.
To suppress those warnings and allow devices to be discovered as before
the offending commit, restrict the phy_mask setting and lowest phy
setting only to the controller phys.
