2025-05-01net: vertexcom: mse102x: Fix possible stuck of SPI interruptStefan Wahren
The MSE102x doesn't provide any SPI commands for interrupt handling. So in case the interrupt fired before the driver requests the IRQ, the interrupt will never fire again. In order to fix this always poll for pending packets after opening the interface.

2025-05-01net: hns3: fix an interrupt residual problemYonglong Liu
When a VF is passthrough to a VM, and the VM is killed, the reported interrupt may not been handled, it will remain, and won't be clear by the nic engine even with a flr or tqp reset. When the VM restart, the interrupt of the first vector may be dropped by the second enable_irq in vfio, see the issue below: https://gitlab.com/qemu-project/qemu/-/issues/2884#note_2423361621 We notice that the vfio has always behaved this way, and the interrupt is a residue of the nic engine, so we fix the problem by moving the vector enable process out of the enable_irq loop.

2025-05-01net: hns3: store rx VLAN tag offload state for VFJian Shen
The VF driver missed to store the rx VLAN tag strip state when user change the rx VLAN tag offload state. And it will default to enable the rx vlan tag strip when re-init VF device after reset. So if user disable rx VLAN tag offload, and trig reset, then the HW will still strip the VLAN tag from packet nad fill into RX BD, but the VF driver will ignore it for rx VLAN tag offload disabled. It may cause the rx VLAN tag dropped.

2025-05-01octeon_ep: Fix host hang issue during device rebootSathesh B Edara
When the host loses heartbeat messages from the device, the driver calls the device-specific ndo_stop function, which frees the resources. If the driver is unloaded in this scenario, it calls ndo_stop again, attempting to free resources that have already been freed, leading to a host hang issue. To resolve this, dev_close should be called instead of the device-specific stop function.dev_close internally calls ndo_stop to stop the network interface and performs additional cleanup tasks. During the driver unload process, if the device is already down, ndo_stop is not called.

On Adva boards, SMA sysfs store/get operations can call __handle_signal_outputs() or __handle_signal_inputs() while the `irig` and `dcf` pointers are uninitialized, leading to a NULL pointer dereference in __handle_signal() and causing a kernel crash. Adva boards don't use `irig` or `dcf` functionality, so add Adva-specific callbacks `ptp_ocp_sma_adva_set_outputs()` and `ptp_ocp_sma_adva_set_inputs()` that avoid invoking `irig` or `dcf` input/output routines.

dcn401_populate_mcm_luts This commit introduces a NULL pointer check for mpc->funcs->program_lut_mode in the dcn401_populate_mcm_luts function. The previous implementation directly called program_lut_mode without validating its existence, which could lead to a NULL pointer dereference. With this change, the function is now only invoked if mpc->funcs->program_lut_mode is not NULL Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:720 dcn401_populate_mcm_luts() error: we previously assumed 'mpc->funcs->program_lut_mode' could be null (see line 701) drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c 642 void dcn401_populate_mcm_luts(struct dc *dc, 643 struct pipe_ctx *pipe_ctx, 644 struct dc_cm2_func_luts mcm_luts, 645 bool lut_bank_a) 646 { ... 716 } 717 if (m_lut_params.pwl) { 718 if (mpc->funcs->mcm.populate_lut) 719 mpc->funcs->mcm.populate_lut(mpc, m_lut_params, lut_bank_a, mpcc_id); --> 720 mpc->funcs->program_lut_mode(mpc, MCM_LUT_SHAPER, MCM_LUT_ENABLE, lut_bank_a, mpcc_id); Cc: Yihan Zhu <yihanzhu@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Cc: Tom Chung <chiahsuan.chung@amd.com> Cc: Roman Li <roman.li@amd.com> Cc: Alex Hung <alex.hung@amd.com> Cc: Aurabindo Pillai <aurabindo.pillai@amd.com> Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Reviewed-by: Yihan Zhu <yihanzhu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Those custom min/max values need to be reset once user switches to auto or restores default settings. Otherwise, they may get used inadvertently during the next operation.
