The original function returned an unsigned int. Why did you use the UL
suffix here?
Also, this line still raises a checkpatch warning about it being over 80
characters. AFAIK, if you change a line in a patch, you should make
sure it doesn't raise any checkpatch warnings afterwards. Don't take my
word for it, though.
