From 9dae4a5ff13701f15f051e3911a83a1e497a4bc3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Noralf=20Tr=C3=B8nnes?= Date: Sun, 27 Feb 2022 13:47:12 +0100 Subject: [PATCH] drm/mipi-dbi: Add driver_private member to struct mipi_dbi_dev MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 1e7e8e1 upstream. 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 Acked-by: Sam Ravnborg Signed-off-by: Noralf Trønnes Signed-off-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20220227124713.39766-5-noralf@tronnes.org --- include/drm/drm_mipi_dbi.h | 8 ++++++++ 1 file changed, 8 insertions(+) --- a/include/drm/drm_mipi_dbi.h +++ b/include/drm/drm_mipi_dbi.h @@ -130,6 +130,14 @@ struct mipi_dbi_dev { * @dbi: MIPI DBI interface */ struct mipi_dbi dbi; + + /** + * @driver_private: Driver private data. + * Necessary for drivers with private data since devm_drm_dev_alloc() + * can't allocate structures that embed a structure which then again + * embeds drm_device. + */ + void *driver_private; }; static inline struct mipi_dbi_dev *drm_to_mipi_dbi_dev(struct drm_device *drm)
