Bug#94792: i2c-source installs modules in wrong directory

[Clemens Wehrmann <clemens@curl.com>]

Package: i2c-source
Version: 2.5.4-3

When i2c-source is turned into a package with make-kpkg for a kernel built
with --append-to-version=-cw, the package has the correct name (with the
appended version), the control file installs doc files and the modutile
file with the full version, but installs the kernel modules into

	/lib/modules/2.4.1/misc

instead of

	/lib/modules/2.4.1-cw/misc

This confuses (unresolved symbols) lm-sensors, which seems to handle this
correctly.  If I symlink the i2c modules from one directory to the other
everything works.

I've compared debian/rules of i2c-source and lm-sensors-source.  The
latter uses

binary-modules: build_modules
	dh_install_dirs lib/modules/$(KVERS)/misc
        find -name \*.o | grep /kernel/ | egrep -v 'RPM|CVS' | \
                xargs -i install -m 0644 {} debian/tmp/lib/modules/$(KVERS)/misc

i2c OTOH doesn't use dh_install_dirs (or KVERS) in the same way, and seems
to just call 'make install' on the package Makefile (which doesn't know
about KVERS).  I'm not sure I have that last part right as I'm new to
Debian and the magic of deb-helper and make-kpkg.

Thanks.
