Use of dev_private is deprecated, so hide it in the helper function to_mga_device(). v2: * make to_mga_device() a function (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20200507090315.21274-2-tzimmermann@suse.de --- diff --git a/drivers/gpu/drm/mgag200/mgag200_cursor.c b/drivers/gpu/drm/mgag200/mgag200_cursor.c index d491edd317ff3..aebc9ce43d551 100644 --- a/drivers/gpu/drm/mgag200/mgag200_cursor.c +++ b/drivers/gpu/drm/mgag200/mgag200_cursor.c @@ -260,7 +260,7 @@ int mgag200_crtc_cursor_set(struct drm_crtc *crtc, struct drm_file *file_priv, uint32_t handle, uint32_t width, uint32_t height) { struct drm_device *dev = crtc->dev; - struct mga_device *mdev = (struct mga_device *)dev->dev_private; + struct mga_device *mdev = to_mga_device(dev); struct drm_gem_object *obj; struct drm_gem_vram_object *gbo = NULL; int ret; @@ -307,7 +307,7 @@ err_drm_gem_object_put_unlocked: int mgag200_crtc_cursor_move(struct drm_crtc *crtc, int x, int y) { - struct mga_device *mdev = (struct mga_device *)crtc->dev->dev_private; + struct mga_device *mdev = to_mga_device(crtc->dev); /* Our origin is at (64,64) */ x += 64; diff --git a/drivers/gpu/drm/mgag200/mgag200_drv.c b/drivers/gpu/drm/mgag200/mgag200_drv.c index 3298b7ef18b03..c2f0e4b40b052 100644 --- a/drivers/gpu/drm/mgag200/mgag200_drv.c +++ b/drivers/gpu/drm/mgag200/mgag200_drv.c @@ -120,7 +120,7 @@ int mgag200_driver_dumb_create(struct drm_file *file, struct drm_device *dev, struct drm_mode_create_dumb *args) { - struct mga_device *mdev = dev->dev_private; + struct mga_device *mdev = to_mga_device(dev); unsigned long pg_align; if (WARN_ONCE(!dev->vram_mm, "VRAM MM not initialized")) diff --git a/drivers/gpu/drm/mgag200/mgag200_drv.h b/drivers/gpu/drm/mgag200/mgag200_drv.h index 9691252d6233f..93e2d232931af 100644 --- a/drivers/gpu/drm/mgag200/mgag200_drv.h +++ b/drivers/gpu/drm/mgag200/mgag200_drv.h @@ -182,6 +182,11 @@ struct mga_device { struct drm_encoder encoder; }; +static inline struct mga_device *to_mga_device(struct drm_device *dev) +{ + return dev->dev_private; +} + static inline enum mga_type mgag200_type_from_driver_data(kernel_ulong_t driver_data) { diff --git a/drivers/gpu/drm/mgag200/mgag200_i2c.c b/drivers/gpu/drm/mgag200/mgag200_i2c.c index 9f4635916d322..09731e614e46d 100644 --- a/drivers/gpu/drm/mgag200/mgag200_i2c.c +++ b/drivers/gpu/drm/mgag200/mgag200_i2c.c @@ -61,34 +61,34 @@ static inline void mga_i2c_set(struct mga_device *mdev, int mask, int state) static void mga_gpio_setsda(void *data, int state) { struct mga_i2c_chan *i2c = data; - struct mga_device *mdev = i2c->dev->dev_private; + struct mga_device *mdev = to_mga_device(i2c->dev); mga_i2c_set(mdev, i2c->data, state); } static void mga_gpio_setscl(void *data, int state) { struct mga_i2c_chan *i2c = data; - struct mga_device *mdev = i2c->dev->dev_private; + struct mga_device *mdev = to_mga_device(i2c->dev); mga_i2c_set(mdev, i2c->clock, state); } static int mga_gpio_getsda(void *data) { struct mga_i2c_chan *i2c = data; - struct mga_device *mdev = i2c->dev->dev_private; + struct mga_device *mdev = to_mga_device(i2c->dev); return (mga_i2c_read_gpio(mdev) & i2c->data) ?
