Thanks for looking into it.

I see your point about making it a single return statement.  I tend to
shorten things as well.  I'd keep it as this:

bool rtw_endofpktfile(const struct pkt_file *pfile_
{
        return pfile->pkt_len == 0;
}

Usign `!` operator suggests the variable is boolean although the name
suggests it isn't.  I'm not so familiar with the linux kernel code base
yet to justify it myself but I see no harm in making it slightly more
explicit.

It looks to me that the original intention was to open a possibility to
define the end of packet file in a OS dependent way so I'd leave it.

Or, if the counter argument is that non-Linux functionality should not
appear in this driver, the rest of non-Linux code should be removed in
the first place.  I'm not in position to even have an opinion on this.

The sole point of this patch was to fix a coding style problem but the
change you suggest seems still relevant.  I'll resend unless you have
strong objections on using `==` operator explicitly in the return statement.

Cheers,
Kris
