Match the subject line style:

dc593fd48abb PCI/VGA: Remove empty vga_arb_device_card_gone()
...
Subject line should be a summary of the commit log, not just "various
style fixes". This one needs to say something about
vga_str_to_iostate().
Ok, thanks for the educating .

To keep consistent with vga_iostate_to_str() function, the third argument
of vga_str_to_iostate() function should be 'unsigned int *'.

Omit all the comment formatting changes. They are distractions from the
vga_str_to_iostate() parameter change.
I think this patch should be the single line change to the
vga_str_to_iostate() prototype so it matches the callers.
If you want to do the other comment formatting changes, they're fine,
but they should be all together in a separate patch that clearly
doesn't change the generated code.
Ok, no problem.
Will be improved at next version.
