This patch avoids that the following warning is reported when building against kernel v4.21: ================= WARNING ================ 'SUBDIRS' will be removed after Linux 5.3 Please use 'M=' or 'KBUILD_EXTMOD' instead ========================================== A quote from an upstream kernel patch: commit 07e5823127155b3a29003aca926f87c9843f6810 Author: Andrew Morton <akpm@osdl.org> Date: Mon Apr 12 01:05:40 2004 -0700 [PATCH] kbuild: external module support From: Sam Ravnborg <sam@ravnborg.org> Based on initial patch from Andreas Gruenbacher there is now better support for building external modules with kbuild. The preferred syntax is now: make -C $KERNELSRC M=$PWD but the old syntax: make -C $KERNELSRC SUBDIRS=$PWD modules will remain supported. git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@7851 d57e44dd-8a1f-0410-8b47-8ef2f437770f
