Thanks for the patch, LGTM. I had in my notes that there's a similar warning in
fs/afs/dir.c
line 138
format specifies type 'unsigned short' but the argument has type 'int'

can you verify if that's still the case, and if so, roll that change
into this one in a v2?

Otherwise, I'll post my reviewed by tag, and we can take just this one.
