12 daysdt-bindings: mfd: ab8500: Add regulatorsLinus Walleij
The buck converters were not initially added to the device tree or drivers as they are mostly always-on, but their outputs supply devices which need to reference the correct regulator. Describe the six AB8500 buck converters when the regulator node uses "stericsson,ab8500-regulator". Describe the AB8505 converters under their native VSMPSA, VSMPSB, VSAFE, VARM, VSMPSC and VSMPSM names when the node uses "stericsson,ab8505-regulator". Keeping the two namespaces conditional on the regulator compatible avoids representing the distinct AB8505 VSAFE and VSMPSC rails with the AB8500 SMPS3 and VAPE node names.

This makes the intended resource type explicit and keeps the definitions consistent with the DA9061 resources. This is a mechanical cleanup with no functional change.

12 daysmfd: da903x: Cancel IRQ work during teardownHongyan Xu
The IRQ handler disables the IRQ and schedules irq_work. Releasing the IRQ does not drain that work, which can continue to use the devm-allocated chip and notifier state. Manage both IRQ-work cancellation and subdevice removal with devres. Register the subdevice-removal action before requesting the IRQ, then add the IRQ-work action after the request. This avoids leaving a live IRQ without work cancellation if action registration fails. Devres cleanup then disables the IRQ and drains the work before releasing the IRQ and removing child devices. Register both actions before creating the children so partial probe failures use the same ordering. This issue was found by the author's in-house static analysis tool. The patch was reviewed by the author against the latest mainline tree.

12 daysdrm/amd/display: Rebuild InfoFrames on output color space changesSatyajit Roy
resource_build_info_frame() derives colorimetry and RGB quantization from stream->output_color_space. A Broadcast RGB-only atomic commit updates that field and reprograms the output CSC, but none of the InfoFrame update predicates include output_color_space. The sink can therefore retain the previous AVI InfoFrame range while the source starts transmitting a different pixel range. Treat an output color space change as an InfoFrame change in update classification and in both stream programming paths. Hardware testing on an HDMI 2.1 television confirmed that its automatic black-level selection follows Full to Limited and Limited to Full transitions in SDR, HDR, and HDR with VRR active, without a modeset or visible link blank.

amdgpu_dm_get_output_color_space() applies the Broadcast RGB connector property to default RGB output, but always selects full-range output for BT.2020 RGB. Consequently, explicitly selecting Limited has no effect on the output CSC or AVI InfoFrame when HDR uses BT.2020 RGB. Select COLOR_SPACE_2020_RGB_LIMITEDRANGE when the output encoding is RGB and Broadcast RGB is Limited. Keep Automatic and Full at full range, and leave YCbCr output unchanged. Add KUnit coverage for limited-range RGB output through both BT.2020 connector colorspace values.

DC uses dc_edid_caps.qs_bit when constructing the HDMI AVI InfoFrame quantization-range field. Although DRM parses the sink capability into drm_display_info, DM never copies it into the DC EDID capabilities. The field therefore remains zero and the AVI quantization range stays at its default value.

With a peer down, every NPA-REVOKE send in amdgpu_ualink_exp_cleanup_worker() wasted ~2s, and the peer stayed ESTABLISHED so each subsequent handle cleanup timed out again, piling up past the 120s hung-task threshold.

Routing through the calcs table lets a future core generation reuse this flow without editing it. [How] Add a static get_calcs(ctx) helper returning ctx->calcs->dcn6. Replace every direct dcn5_*/dcn6_* calcs call with get_calcs(ctx)->slot(...). dcn6_populate_mode_programming() did not previously receive the mp context, so thread calc_mp_ctx through it to reach get_calcs() for its three calcs calls. Assign ctx->calcs from core->calcs in dcn6_mp_build_calculate_mp_context().

[Why] DCN6 core mode support/programming call DCN5 and DCN6 calcs functions directly by name. The calcs layer needs one seam the funcs layer can go through instead of hardcoding a generation. [How] Add union dml2_core_calcs holding one function pointer table per generation, plus a calcs field on dml2_core_instance and on the mode support/programming contexts. Add dml2_core_dcn6_calcs.c/.h defining struct dml2_core_dcn6_calcs, a flat table covering every DCN6 calcs function and every DCN5 calcs function DCN6 reuses, and dml2_core_dcn6_calcs_init() to populate it.

12 daysselftests: tc-testing: test action batch failure cleanupXuanqiang Luo
Add tests for cleanup after a batched RTM_NEWACTION request fails. Replace an existing gact action bound to a filter, then fail a later entry by requesting goto chain without a classifier context. Check that the bound action's reference count returns to its original value. Also cover a successfully initialized new action between the bound action and the failing entry, verifying that its reserved index can be reused. Repeat the bound action in another batch to check that each temporary reference to the same action is released.

12 daysnet/sched: act_api: release all action references on NEWACTION failureXuanqiang Luo
When a batched RTM_NEWACTION request replaces an existing action, tcf_idr_check_alloc() takes a temporary reference on it. If a later action fails to initialize, tcf_action_destroy() uses strict release semantics to clean up the actions initialized so far. For an action bound to a filter, the strict check returns -EPERM without dropping the temporary reference. This error also makes tcf_action_destroy() return before releasing subsequent entries. Any new action initialized between the bound action and the failing entry is leaked together with its reserved IDR slot, preventing reuse of its index. Use tcf_idr_release() to drop each reference held by the batch without rejecting bound actions. This allows cleanup to continue through all initialized entries and preserves the module reference release when an action is destroyed. Explicit action deletion and flushing retain their separate bind-count checks.
