Dan Carpenter eddad30e74 ntb_hw_switchtec: potential shift wrapping bug in switchtec_ntb_init_sndev()
[ Upstream commit ff148d8ac5 ]

This code triggers a Smatch warning:

    drivers/ntb/hw/mscc/ntb_hw_switchtec.c:884 switchtec_ntb_init_sndev()
    warn: should '(1 << sndev->peer_partition)' be a 64 bit type?

The "part_map" and "tpart_vec" variables are u64 type so this seems like
a valid warning.
