ntb_hw_switchtec: potential shift wrapping bug in switchtec_ntb_init_sndev()
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.
