Subject: [PATCH] Fix warning when building fs/afs/super.c


Fix build waning in fs/afs/super.c

fs/afs/super.c: In function 'afs_parse_options':
fs/afs/super.c:153: warning: passing argument 2 of 'match_token' discards qualifiers from pointer target type

AFS declares it's match_table as const, which is discrded in lib/parser.c.
match_token() doesn't modify the table so making it const should be safe.
