Subject: [Buildroot] [PATCH v2 06/23] linux/extensions: point to proper _SRCDIR and @D
Date: Wed, 28 Oct 2026 14:37:27 -0700	[thread overview]
Message-ID: <20261028213744.511429-7-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20261028213744.511429-1-florian.fainelli@broadcom.com>

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

In preparation for the split between the source and build directories,
make the linux extensions look in the correct locations.

The patches or scripts are located in the source direcotries of the
extensions, so look there.

Also, the externsions are run as part of the various infra hooks, so
they have access to @D, so use that instead of LINUX_DIR.
