Subject: kbuild: compute the dtbs_install destination more simply
X-Git-Tag: v5.7-rc1~151^2~12
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2431f22a911a6130a10b4a0c6f13d10ede007d39;p=thirdparty%2Fkernel%2Flinux.git

kbuild: compute the dtbs_install destination more simply

The 'dtbinst_root' is used to remember the root of the in-kernel dts
directory (i.e. arch/*/boot/dts), but it looks clumsy.

I prefer using two variables 'obj' and 'dst' to track the in-kernel
directory and the install destination, respectively.
