[PATCH] Fix for warning in MODPOST

[Pavel Roskin]

Hello!

When compiling hostap for 2.5.x kernels and it depends on some other
modules (in particular, hostap_cs can depend on ds), there are spurious
warnings:

  Starting the build. KBUILD_BUILTIN= KBUILD_MODULES=1
  Building modules, stage 2.
  MODPOST
*** Warning: "pcmcia_unregister_driver"
[/home/proski/src/hostap/driver/modules/hostap_cs.ko] undefined!
*** Warning: "pcmcia_register_driver"
[/home/proski/src/hostap/driver/modules/hostap_cs.ko] undefined!
*** Warning: "cs_error"
[/home/proski/src/hostap/driver/modules/hostap_cs.ko] undefined!
*** Warning: "CardServices"
[/home/proski/src/hostap/driver/modules/hostap_cs.ko] undefined!

This is especially visible for 2.5.70 kernel that defaults to the quiet
build.  We need to do it better.

The attached patch (checking that it's indeed attached :-)) copies
.tmp_versions from the kernel sources to driver/modules.  This directory
together with the *.mod files is removed by "make clean".
"driver/modules" has been replaced with $(MSRC) everywhere for
consistency.

driver/modules/.cvsignore has been changed to include .tmp_versions and
*.ver files.  The later are created when building hostap for 2.4.x
kernels.
