From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 13 Feb 2024 10:28:36 +0100 Subject: [PATCH] ARM: Don't mention the full path of the source directory in mach-types.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To make package building reproducible independent of the location of the source tree, the absolute path of this source tree must not be mentioned in the built artifact. So strip $abs_srctree from FILENAME in the output. This fixes a warning issued by Yocto: WARNING: linux-lxatac-6.7-r0 do_package_qa: QA Issue: File /usr/src/debug/linux-lxatac/6.7-r0/arch/arm/include/generated/asm/mach-types.h in package linux-lxatac-src contains reference to TMPDIR The patch was denied upstream with the following comment by Russel King: Or just leave it as is. It's in a comment, it doesn't get into the executable, and thus is harmless.
