From 70a59dd82959f828220bf3f5f336e1b8fd931d15 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 4 Nov 2020 11:04:24 +0100 Subject: drm/: Constify struct drm_driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg Cc: kernel test robot Acked-by: Maxime Ripard Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Cc: Sam Ravnborg Cc: Dave Airlie Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: Christian König Cc: Eric Anholt Cc: Maxime Ripard Cc: Ben Skeggs Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch --- drivers/gpu/drm/tegra/drm.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'drivers/gpu/drm/tegra/drm.c') diff --git a/drivers/gpu/drm/tegra/drm.c b/drivers/gpu/drm/tegra/drm.c index f0f581cd345e..19ffb0626505 100644 --- a/drivers/gpu/drm/tegra/drm.c +++ b/drivers/gpu/drm/tegra/drm.c @@ -847,7 +847,7 @@ static void tegra_debugfs_init(struct drm_minor *minor) } #endif -static struct drm_driver tegra_drm_driver = { +static const struct drm_driver tegra_drm_driver = { .driver_features = DRIVER_MODESET | DRIVER_GEM | DRIVER_ATOMIC | DRIVER_RENDER, .open = tegra_drm_open, @@ -1081,12 +1081,11 @@ static bool host1x_drm_wants_iommu(struct host1x_device *dev) static int host1x_drm_probe(struct host1x_device *dev) { - struct drm_driver *driver = &tegra_drm_driver; struct tegra_drm *tegra; struct drm_device *drm; int err; - drm = drm_dev_alloc(driver, &dev->dev); + drm = drm_dev_alloc(&tegra_drm_driver, &dev->dev); if (IS_ERR(drm)) return PTR_ERR(drm); -- cgit v1.2.3
