[PATCH] kbuild: deb-pkg: Fix build error caused by lack of positionnal argument

[PATCH] kbuild: deb-pkg: Fix build error caused by lack of positionnal argument

[Marc Zyngier]

Since 8ef052389f7f ("kbuild: package: add -e and -u options to some
shell scripts"), building a debian package on my arm64 box fails:

$ make -j20 bindeb-pkg
  UPD     include/config/kernel.release
  GEN     debian
./scripts/package/mkdebian: 138: 1: parameter not set
make[2]: *** [scripts/Makefile.package:98: debian] Error 2
make[1]: *** [/home/maz/hot-poop/arm-platforms/Makefile:1538: bindeb-pkg] Error 2
make: *** [Makefile:224: __sub-make] Error 2

Applying the same pattern for substitution of undefined variables
seems to paper over the issue and brings the script back to life.

This is wrong.

It will break 'make srcdeb-pkg' because
"set" = "--need-source" is always false.



I will squash the following.


while [ $# -gt 0 ]; do
    case "$1" in
    --need-source)
        gen_source
        shift
        ;;
    *)
        break
        ;;
    esac
done


Thanks for the report.
