Driver core holds a reference to the USB interface and its parent USB device while the interface is bound to a driver and there is no need to take additional references unless the structures are needed after disconnect. This driver takes a reference to the USB device during probe but does not to release it on all probe errors (e.g. when descriptor parsing fails). Drop the redundant device reference to fix the leak, reduce cargo culting, make it easier to spot drivers where an extra reference is needed, and reduce the risk of further memory leaks.

2026-03-16wifi: rtl8xxxu: fix potential use of uninitialized valueYi Cong
The local variables 'mcs' and 'nss' in rtl8xxxu_update_ra_report() are passed to rtl8xxxu_desc_to_mcsrate() as output parameters. If the helper function encounters an unhandled rate index, it may return without setting these values, leading to the use of uninitialized stack data. Remove the helper rtl8xxxu_desc_to_mcsrate() and inline the logic into rtl8xxxu_update_ra_report(). This fixes the use of uninitialized 'mcs' and 'nss' variables for legacy rates. The new implementation explicitly handles: - Legacy rates: Set bitrate only. - HT rates (MCS0-15): Set MCS flags, index, and NSS (1 or 2) directly. - Invalid rates: Return early.

2026-03-06wifi: move action code from per-type frame structsJohannes Berg
The action code actually serves to identify the type of action frame, so it really isn't part of the per-type structure. Pull it out and have it in the general action frame format. In theory, whether or not the action code is present in this way is up to each category, but all categories that are defined right now all have that value. While at it, and since this change requires changing all users, remove the 'u' and make it an anonymous union in this case, so that all code using this changes. Change IEEE80211_MIN_ACTION_SIZE to take an argument which says how much of the frame is needed, e.g. category, action_code or the specific frame type that's defined in the union. Again this also ensures that all code is updated. In some cases, fix bugs where the SKB length was checked after having accessed beyond the checked length, in particular in FTM code, e.g. ieee80211_is_ftm().

2026-03-03wifi: rtlwifi: pci: fix possible use-after-free caused by unfinished ↵Duoming Zhou
irq_prepare_bcn_tasklet The irq_prepare_bcn_tasklet is initialized in rtl_pci_init() and scheduled when RTL_IMR_BCNINT interrupt is triggered by hardware. But it is never killed in rtl_pci_deinit(). When the rtlwifi card probe fails or is being detached, the ieee80211_hw is deallocated. However, irq_prepare_bcn_tasklet may still be running or pending, leading to use-after-free when the freed ieee80211_hw is accessed in _rtl_pci_prepare_bcn_tasklet(). Similar to irq_tasklet, add tasklet_kill() in rtl_pci_deinit() to ensure that irq_prepare_bcn_tasklet is properly terminated before the ieee80211_hw is released.

pci_upstream_bridge() returns NULL if the device is on a root bus. If 8821CE is installed in the system with such a PCI topology, the probing routine will crash. This has probably been unnoticed as 8821CE is mostly supplied in laptops where there is a PCI-to-PCI bridge located upstream from the device. However the card might be installed on a system with different configuration. Check if the bridge does exist for the specific workaround to be applied.

Some chipsets, e.g. Wi-Fi 7, will not record SER (system error recovery), which are triggered by simulations, in the HW counters. Their HW counters only record the SER happen in field. However for verification, it's still needed to check if simulations are triggered. So, add SW counters to count any causes that SER happen. But, SW can only count L1 and L2.

2026-03-03wifi: rtw89: add general way to generate module firmware stringZong-Zhe Yang
Module firmware string depends on max format of the firmware. When max format is 0, the module firmware string will be like XYZ.bin. However, when max format N > 0, the module firmware string will become XYZ-N.bin. Originally, when one chip updated its max firmware format from 0 to 1, the module firmware string also needed to be changed. However, did not need to do for other cases, e.g. from 1 to 2. It's a bit inconvenient to always remember that from 0 to 1 is a special case. So, add a general macro to generate the corresponding module firmware string based on max firmware format.

RTL8851BU and RTL8852BU currently have much lower TX speed than expected, ~100 and ~300 Mbps, respectively. This is because part of the chip's memory is allocated for some unknown firmware features instead of the TX buffers. The vendor drivers have a module parameter called "rtw_quota_turbo_en", which can be used to choose between full TX speed or the unknown firmware features. It is on by default. Change the relevant chip parameters to implement the turbo mode. Do it only for USB because PCI is already fast even without the turbo mode. It's unclear if SDIO will need it or not.

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Many network drivers have unnecessary empty module_init and module_exit functions. Remove them (including some that just print a message). Note that if a module_init function exists, a module_exit function must also exist; otherwise, the module cannot be unloaded.

SPS OCP (over current protection) is a mechanism to cut off power to protect hardware. When this happens, raise an interrupt to signal driver, which prints out a message to note hardware status.

2026-01-28wifi: rtw89: get designated link to replace link instance 0Zong-Zhe Yang
Clean up some places where still to get link instance 0 directly. Since now MLSR switch is supported, it's not guaranteed to always run on link instance 0. So, prefer to get designated link in most cases. For now, the only exception is MCC (multi-channel concurrency) case. How to fill content of its H2C command depends on how to choose link instance, so cannot simply change it as above. Will handle MCC case separately afterwards.
