Subject: [PATCH v2 2/3] drm/mipi-dbi: Add driver_private member to struct mipi_dbi_dev
Date: Tue, 25 Jan 2022 18:56:59 +0100	[thread overview]
Message-ID: <20220125175700.37408-3-noralf@tronnes.org> (raw)
In-Reply-To: <20220125175700.37408-1-noralf@tronnes.org>

devm_drm_dev_alloc() can't allocate structures that embed a structure
which then again embeds drm_device. Workaround this by adding a
driver_private pointer to struct mipi_dbi_dev which the driver can use for
its additional state.
