This resulted in "comparision of distinct pointer types lacks a cast" build warnings on non X86 architectures [2,3].

'resid' is inside a while loop which is only entered if it is positive. Casting it as a __u32 can be perormed without a loss of data or change in functionality. Fix the warning by casting 'resid' as a __u32. Reported-by: kbuild test robot Signed-off-by: Jeremiah Mahler Signed-off-by: Greg Kroah-Hartman --- Reading git-diff-tree failed
