Subject: [PATCH 01/22] gpu/drm: remove the shmobile drm driver
Date:   Fri, 13 Jan 2023 07:23:18 +0100
Message-Id: <20230113062339.1909087-2-hch@lst.de>
In-Reply-To: <20230113062339.1909087-1-hch@lst.de>
References: <20230113062339.1909087-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

This driver depends on ARM && ARCH_SHMOBILE, but ARCH_SHMOBILE can only be
set for each/sh, making the driver dead code except for the COMPILE_TEST
case.
