Subject: fs/reiserfs/xattr.c: force type conversion in xattr_hash
This patch fixes the sparse warning:
fs/reiserfs//xattr.c:453:28: warning: incorrect type in return
expression (different base types)
fs/reiserfs//xattr.c:453:28: expected unsigned int
fs/reiserfs//xattr.c:453:28: got restricted __wsum
fs/reiserfs//xattr.c:453:28: warning: incorrect type in return
expression (different base types)
fs/reiserfs//xattr.c:453:28: expected unsigned int
fs/reiserfs//xattr.c:453:28: got restricted __wsum
csum_partial returns restricted integer __wsum whereas xattr_hash
expects a return type of __u32.
