treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

drm: remove driver date from struct drm_driver and all drivers

2024-12-05T10:35:42Z

We stopped using the driver initialized date in commit 7fb8af6798e8 ("drm: deprecate driver date") and (eventually) started returning "0" for drm_version ioctl instead. Finish the job, and remove the unused date member from struct drm_driver, its initialization from drivers, along with the common DRIVER_DATE macros. v2: Also update drivers/accel (kernel test robot) Reviewed-by: Javier Martinez Canillas Acked-by: Alex Deucher Acked-by: Simon Ser Acked-by: Jeffrey Hugo Acked-by: Lucas De Marchi Acked-by: Dmitry Baryshkov # msm Reviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/1f2bf2543aed270a06f6c707fd6ed1b78bf16712.1733322525.git.jani.nikula@intel.com Signed-off-by: Jani Nikula

drm/gud: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann Cc: "Noralf Trønnes" Acked-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-55-tzimmermann@suse.de

drm: add missing MODULE_DESCRIPTION() macros

drm/format-helper: Pass format-conversion state to helpers

2023-11-14T09:16:53Z

Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Tested-by: Javier Martinez Canillas # ssd130x Cc: Noralf Trønnes Cc: Javier Martinez Canillas Cc: Gerd Hoffmann Cc: David Lechner Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-4-tzimmermann@suse.de

drm/gud: Use size_add() in call to struct_size()

2023-09-29T21:48:32Z

If, for any reason, the open-coded arithmetic causes a wraparound, the protection that `struct_size()` adds against potential integer overflows is defeated. Fix this by hardening call to `struct_size()` with `size_add()`. Fixes: 40e1a70b4aed ("drm: Add GUD USB Display driver") Signed-off-by: "Gustavo A. R.
