Bug#710900: nvidia-kernel-legacy-173xx-source: Fails to build debian package under user-compiled kernels (kernel version string problem).

[Felix Becker]

Package: nvidia-kernel-legacy-173xx-source
Version: 173.14.35
Severity: important

The debian build rules are not clean for user compiled kernels which
include in the kernel version characters which are not allowed in
debian package version strings.

A run of 'fakeroot debian/rules binary':

Attached is a quick and dirty patch which resolves the problem for my
machine; it is a patch to 'debian/prep-modules'

Applies to at least the packages 'nvidia-kernel-legacy-173xx-source'
and 'nvidia-kernel-legacy-96xx-source', not tested with others. Applies
at least to package in wheezy (stable).

While reporting this bug, a compilation of
'nvidia-kernel-legacy-96xx-source' is installed, but exactly same
problem (and exactly same solution) to
'nvidia-kernel-legacy-173xx-source'.
