Subject: kbuild: deb-pkg: do not build linux-headers package if CONFIG_MODULES=n
X-Git-Tag: xarray-5.12~1146^2~5
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=bac977cbc0d6731fb8e67c2be0e4acbd959e10b3;p=users%2Fwilly%2Fxarray.git

kbuild: deb-pkg: do not build linux-headers package if CONFIG_MODULES=n

Since commit 269a535ca931 ("modpost: generate vmlinux.symvers and
reuse it for the second modpost"), with CONFIG_MODULES disabled,
"make deb-pkg" (or "make bindeb-pkg") fails with:

  find: ‘Module.symvers’: No such file or directory

If CONFIG_MODULES is disabled, it doesn't really make sense to build
the linux-headers package.

Fixes: 269a535ca931 ("modpost: generate vmlinux.symvers and reuse it for the second modpost")
