"git log --oneline <file>" is a good guide in general and could be
used for other patches in this series as well.

Let's not use the checkpatch "$max_line_length = 100" as a guide.

The pci-hyperv.c file as a whole is obviously formatted to fit in 80
columns with few exceptions.

IMO it would not be an improvement to scatter random 100-column lines
throughout.  That would just mean the file would look bad in an
80-column terminal and there would be a lot of wasted space in a
100-column terminal.
