drm/tve200: add OF module alias for autoloading

2026-07-24T07:21:03+00:00

The TVE200 DRM driver can be built as a module and uses tve200_of_match as its OF match table, but the table is not exported for module alias generation. Add the MODULE_DEVICE_TABLE(of, ...) entry so modpost can generate OF module aliases for OF based module autoloading.

drm/panel: of_drm_find_panel() return a counted reference

2026-07-20T13:07:22+00:00

Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge() receive a pointer with no reference held, creating a window where the panel device can be unregistered and freed between the lookup and first use (e.g., drm_panel_prepare()). Fix the lookup function by acquiring a reference with drm_panel_get() before returning, under panel_lock. Callers are now responsible for calling drm_panel_put() when they no longer need the pointer. For bridge drivers that immediately wrap the panel in a panel_bridge (which acquires its own reference), release the lookup reference right after the bridge creation call. For analogix-anx6345, which stores the panel for direct use, release the reference in the i2c remove path. For platform drivers using analogix_dp_core with a component lifecycle (exynos_dp, rockchip analogix_dp), release the lookup reference in the platform remove() function. The panel_bridge created during bind() holds a separate reference that devm cleanup releases after remove() returns. Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in bridge/panel.c itself, update a second batch of drivers calling of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the lookup reference after wrapping the panel in a bridge, and handle the cases where a panel is found but cannot be used, dropping the reference immediately in those paths.

drm/tve200: Fix probe cleanup after register failure

2026-05-05T09:16:39+00:00

tve200_modeset_init() creates a panel bridge and initializes the DRM mode config before tve200_probe() registers the DRM device. If drm_dev_register() fails, probe returns an error and the driver's remove callback is not called, so those modeset resources are left behind. Unwind the panel bridge and mode config on that failure path before disabling the clock and dropping the DRM device reference.

drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.

drm: remove driver date from struct drm_driver and all drivers

We stopped using the driver initialized date in commit 7fb8af6798e8 ("drm: deprecate driver date") and (eventually) started returning "0" for drm_version ioctl instead.

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43+00:00

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds
