I wanted to remove the #include "hostap_ioctl.c" from hostap.c and build
hostap_ioctl.c separately, but this doesn't work since hostap.c has the
same name as the module.
After renaming hostap.c this will be possible.

Is this patch changing anything in hostap.c or is it just a rename of
the file? Patch file is not exactly ideal for this kind of changes and I
hope git has a better way of storing this kind of rename.
I would rather not rename the file, but if this is the only way of
getting the module built in pieces, I'm okay with the change (assuming
nothing else changed in hostap.c in this changeset).

Why were the hostap_{cs,plx,pci} lines changed? I prefer the original
version of those lines (i.e., no extra padding).

There's no other change.
If you agree, Jeff might be able to do the
mv drivers/net/wireless/hostap/hostap.c \
drivers/net/wireless/hostap/hostap_main.c
plus applying the patch below.

AFAIK you can't build a module hostap.o consisting of multiple objects
with the source files of one of them named hostap.c (Sam Cc'ed for this).

<-- snip -->
I wanted to remove the #include "hostap_ioctl.c" from hostap.c and build
hostap_ioctl.c separately, but this doesn't work since hostap.c has the
same name as the module.
After renaming hostap.c this will be possible.
