fs/affs: use unsigned int for string lengths
- Some min() were used with different types. - Create a new variable in __affs_hash_dentry() to process affs_check_name()/min() return Signed-off-by: Fabian Frederick <fabf@skynet.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
