drm/mipi-dbi: Add driver_private member to struct mipi_dbi_dev
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. v3: - Add documentation Acked-by: Maxime Ripard <maxime@cerno.tech> Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20220227124713.39766-5-noralf@tronnes.org
