Subject[PATCH AUTOSEL 5.10 14/17] cifs: fix the out of range assignment to bit fields in parse_server_interfaces
Date
From: Hyunchul Lee <hyc.lee@gmail.com>

[ Upstream commit c9c9c6815f9004ee1ec87401ed0796853bd70f1b ]

Because the out of range assignment to bit fields
are compiler-dependant, the fields could have wrong
value.
