[PATCH] Fix bug in fs/ecryptfs/inode.c: ecryptfs_encode_filename()
        returns int (with possible negative error value), not
        unsigned int. Both callers in the file get it wrong (they
        are also the only callers of this function). Found by gcc
        extra warning flags (the return value is checked to be < 0,
        which is pointless with unsigned). Compile tested only, but
        should be OK, as the value computed in the function
        internally is int too.
