[PATCH 6.6 504/568] lib/build_OID_registry: dont mention the full path of the script in output

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>

commit 5ef6dc08cfde240b8c748733759185646e654570 upstream.

This change strips the full path of the script generating
lib/oid_registry_data.c to just lib/build_OID_registry.  The motivation
for this change is Yocto emitting a build warning

	File /usr/src/debug/linux-lxatac/6.7-r0/lib/oid_registry_data.c in package linux-lxatac-src contains reference to TMPDIR [buildpaths]

So this change brings us one step closer to make the build result
reproducible independent of the build path.
