mm: introduce vma_get_page_prot() and use it

2026-08-07T01:57:03+00:00

There's a large number of vm_get_page_prot(vma->vm_flags) invocations. Make life easier by introducing vma_get_page_prot() parameterised by the VMA. This also makes converting vm_get_page_prot() to vma_flags_t easier. Also update the userland VMA tests to reflect the change. No functional change intended.

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/rockchip: Remove dependency on DRM simple helpers

2026-07-06T18:27:44+00:00

Simple KMS helper are deprecated since they only add an intermediate layer between drivers and the atomic modesetting. This patch removes the drm_simple_encoder_init() helper usage in the rockchip drivers by open coding it and using the encoder atomic helpers directly. This is a step to eventually get rid of this simple KMS helper, once all drivers that use it have been converted.
