2023-09-21i2c: mux: gpio: Add missing fwnode_handle_put()Liang He
In i2c_mux_gpio_probe_fw(), we should add fwnode_handle_put() when break out of the iteration device_for_each_child_node() as it will automatically increase and decrease the refcounter.

2023-09-21sfc: handle error pointers returned by rhashtable_lookup_get_insert_fast()Edward Cree
Several places in TC offload code assumed that the return from rhashtable_lookup_get_insert_fast() was always either NULL or a valid pointer to an existing entry, but in fact that function can return an error pointer. In that case, perform the usual cleanup of the newly created entry, then pass up the error, rather than attempting to take a reference on the old entry.

2023-09-21wifi: ath11k: fix boot failure with one MSI vectorBaochen Qiang
Commit 5b32b6dd96633 ("ath11k: Remove core PCI references from PCI common code") breaks with one MSI vector because it moves affinity setting after IRQ request, see below log: [ 1417.278835] ath11k_pci 0000:02:00.0: failed to receive control response completion, polling.. [ 1418.302829] ath11k_pci 0000:02:00.0: Service connect timeout [ 1418.302833] ath11k_pci 0000:02:00.0: failed to connect to HTT: -110 [ 1418.303669] ath11k_pci 0000:02:00.0: failed to start core: -110 The detail is, if do affinity request after IRQ activated, which is done in request_irq(), kernel caches that request and returns success directly. Later when a subsequent MHI interrupt is fired, kernel will do the real affinity setting work, as a result, changs the MSI vector. However at that time host has configured old vector to hardware, so host never receives CE or DP interrupts. Fix it by setting affinity before registering MHI controller where host is, for the first time, doing IRQ request.

2023-09-21igc: Expose tx-usecs coalesce setting to userMuhammad Husaini Zulkifli
When users attempt to obtain the coalesce setting using the ethtool command, current code always returns 0 for tx-usecs. This is because I225/6 always uses a queue pair setting, hence tx_coalesce_usecs does not return a value during the igc_ethtool_get_coalesce() callback process. The pair queue condition checking in igc_ethtool_get_coalesce() is removed by this patch so that the user gets information of the value of tx-usecs. Even if i225/6 is using queue pair setting, there is no harm in notifying the user of the tx-usecs. The implementation of the current code may have previously been a copy of the legacy code i210. Since I225 has the queue pair setting enabled, tx-usecs will always adhere to the user-set rx-usecs value. An error message will appear when the user attempts to set the tx-usecs value for the input parameters because, by default, they should only set the rx-usecs value. This patch also adds the helper function to get the previous rx coalesce value similar to tx coalesce. How to test: User can get the coalesce value using ethtool command. Example command: Get: ethtool -c <interface> Previous output: rx-usecs: 3 rx-frames: n/a rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 0 tx-frames: n/a tx-usecs-irq: n/a tx-frames-irq: n/a New output: rx-usecs: 3 rx-frames: n/a rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 3 tx-frames: n/a tx-usecs-irq: n/a tx-frames-irq: n/a Fixes: 8c5ad0dae93c ("igc: Add ethtool support") Signed-off-by: Muhammad Husaini Zulkifli <muhammad.husaini.zulkifli@intel.com> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Link: https://lore.kernel.org/r/20230919170331.1581031-1-anthony.l.nguyen@intel.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-09-20drm/amd/display: fix the ability to use lower resolution modes on eDPHamza Mahfooz
On eDP we can receive invalid modes from dm_update_crtc_state() for entirely new streams for which drm_mode_set_crtcinfo() shouldn't be called on. So, instead of calling drm_mode_set_crtcinfo() from within create_stream_for_sink() we can instead call it from amdgpu_dm_connector_mode_valid(). Since, we are guaranteed to only call drm_mode_set_crtcinfo() for valid modes from that function (invalid modes are rejected by that callback) and that is the only user of create_validate_stream_for_sink() that we need to call drm_mode_set_crtcinfo() for (as before commit cb841d27b876 ("drm/amd/display: Always pass connector_state to stream validation"), that is the only place where create_validate_stream_for_sink()'s dm_state was NULL).

2023-09-20drm/amdgpu: fix a memory leak in amdgpu_ras_feature_enableCong Liu
This patch fixes a memory leak in the amdgpu_ras_feature_enable() function. The leak occurs when the function sends a command to the firmware to enable or disable a RAS feature for a GFX block. If the command fails, the kfree() function is not called to free the info memory.

2023-09-20ice: Auxbus devices & driver for E822 TSMichal Michalik
There is a problem in HW in E822-based devices leading to race condition. It might happen that, in order: - PF0 (which owns the PHC) requests few timestamps, - PF1 requests a timestamp, - interrupt is being triggered and both PF0 and PF1 threads are woken up, - PF0 got one timestamp, still waiting for others so not going to sleep, - PF1 gets it's timestamp, process it and go to sleep, - PF1 requests a timestamp again, - just before PF0 goes to sleep timestamp of PF1 appear, - PF0 finishes all it's timestamps and go to sleep (PF1 also sleeping). That leaves PF1 timestamp memory not read, which lead to blocking the next interrupt from arriving. Fix it by adding auxiliary devices and only one driver to handle all the timestamps for all PF's by PHC owner. In the past each PF requested it's own timestamps and process it from the start till the end which causes problem described above. Currently each PF requests the timestamps as before, but the actual reading of the completed timestamps is being done by the PTP auxiliary driver, which is registered by the PF which owns PHC. Additionally, the newly introduced auxiliary driver/devices for PTP clock owner will be used for other features in all products (including E810).
