Subject: kbuild: deb-pkg: do not take KERNELRELEASE from the source version
X-Git-Tag: v6.6.17~5285^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7a531c21f83d7c62825d00bee3a76c1ccfb5de9f;p=platform%2Fkernel%2Flinux-rpi.git

kbuild: deb-pkg: do not take KERNELRELEASE from the source version

KERNELRELEASE does not need to match the package version in changelog.
Rather, it conventially matches what is called 'ABINAME', which is a
part of the binary package names.

Both are the same by default, but the former might be overridden by
KDEB_PKGVERSION. In this case, the resulting package would not boot
because /lib/modules/$(uname -r) does not point the module directory.

Partially revert 3ab18a625ce4 ("kbuild: deb-pkg: improve the usability
of source package").
