Subject: [Buildroot] [PATCH v2 22/23] package: read kernel headers from LINUX_SRCDIR
Date: Wed, 28 Oct 2026 14:37:43 -0700	[thread overview]
Message-ID: <20261028213744.511429-23-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20261028213744.511429-1-florian.fainelli@broadcom.com>

When the kernel is built out of tree, LINUX_DIR is the build directory and
does not contain the source headers.
