Subject: [PATCH v8 01/15] PCI/TSM: Move core code into its own directory
Date: Wed, 4 Nov 2026 21:46:18 +0530 [thread overview]
Message-ID: <20261104161632.3547423-2-aneesh.kumar@kernel.org> (raw)
In-Reply-To: <20261104161632.3547423-1-aneesh.kumar@kernel.org>
Multiple patch series modify drivers/pci/tsm.c, and some add new files
to the PCI/TSM subsystem. Move tsm.c to tsm/core.c so these series can
share the directory layout and reduce merge conflicts.
Update the build rules, local header include, and MAINTAINERS entry for
the new location.
No functional change.
