treewide: refresh kmalloc_obj() conversionsThis is another run of the Coccinelle script for converting kmalloc()family of allocations to kmalloc_obj() via the existing rules inscripts/coccinelle/api/kmalloc_objs.cocciThis catches both the set of kmalloc() uses added since the firstkmalloc_obj() conversions in v7.0 and adds a large group missed in thefirst pass due to Coccinelle not interacting well with the cleanup.hscoped_...() family of macros[1]. I worked around this with spatch's"--macro-file" argument to a file with all the scoped_...() macros mappedto Coccinelle's YACFE_ITERATOR[2] as that was the closest viable controlflow indicator I could find.Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,riscv, and s390 with no new warnings.Link: https://lore.kernel.org/lkml/202609021314.8A9C0B8@keescook/ [1]Link: https://github.com/coccinelle/coccinelle/blob/master/standard.h [2]Signed-off-by: Kees Cook List of files: /linux/drivers/hid/hid-steelseries-arctis.c

83e70ced0d16eaa22425f93e63af2bb87ffaf4eb - HID: steelseries: Add support for Arctis Nova 5X and Nova 7 families

Mon, 03 Aug 2026 21:15:53 +0200

HID: steelseries: Add support for Arctis Nova 5X and Nova 7 familiesThe Arctis Nova 5X, Nova 7 Gen2, and Nova 7 2026 refresh headsets answerstatus polls, but also send unsolicited battery and connection updateson a second HID interface (interface 5). Use that interface throughasync_interface so the driver does not have to poll. Add request andparse helpers for the Nova status format (0xb0/0xb7/0xb9/0xbb opcodes).The original (pre-Gen2) Arctis Nova 7 family answers the same statusopcodes on the same interfaces, but reports battery capacity as adiscrete 0-4 level instead of a raw percentage. Add a second parsefunction that maps that level through steelseries_map_capacity(), and aseparate device_info so the two capacity encodings cannot get mixed up.Add the fourteen USB product IDs that share these protocols: 0x2253 Arctis Nova 5X 0x2202 Arctis Nova 7 0x2206 Arctis Nova 7X 0x22a4 Arctis Nova 7X (alternate PID) 0x223a Arctis Nova 7 Diablo 0x227a Arctis Nova 7 World of Warcraft Edition 0x22a1 Arctis Nova 7 2026 0x22a7 Arctis Nova 7P 2026 0x22a5 Arctis Nova 7X 2026 0x22a9 Arctis Nova 7 Diablo 2026 0x227e Arctis Nova 7 Gen 2 0x2258 Arctis Nova 7X Gen 2 0x229e Arctis Nova 7X Gen 2 (alternate PID) 0x22ad Arctis Nova 7X Gen 2 (alternate PID)Signed-off-by: Sriman Achanta Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-steelseries-arctis.c

bebeca20ab377dc0d28ca7f3400c6008ba7f15af - HID: steelseries: Add async status interface support

Mon, 03 Aug 2026 21:15:52 +0200

HID: steelseries: Add async status interface supportSome headsets expose a second HID interface that sends battery andconnection updates on its own. Watching that interface lets the driverstop polling the sync interface. Add asteelseries_device_info::async_interface field and the code to handleit: - The driver binds both the sync and async interfaces. The async interface shares the steelseries_device created by the sync interface. It finds the sibling with usb_ifnum_to_if(), and before trusting its intfdata it rejects non-HID siblings by descriptor class and holds the sibling's device lock across the lookup, so a crafted device cannot cause a type-confused read and a concurrent unbind cannot free the hid_device from under it. It then takes a reference and returns -EPROBE_DEFER until the sync interface has probed. If the sync interface never binds, the async interface defers forever, which is fine here. - raw_event() now holds sd->lock and re-checks sd->removed so events on either interface are serialised against removal. - status_work runs once for async devices instead of rearming. A single status request is sent when the headset connects to get the initial battery level.No device sets async_interface yet. This is the infrastructure for thenext commit.Signed-off-by: Sriman Achanta Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-steelseries-arctis.c

Mon, 03 Aug 2026 21:15:51 +0200

HID: steelseries: Manage battery lifetime with refcountingThe next change shares one steelseries_device between two HIDinterfaces, so the state can outlive either interface. Stop using devmfor it. Reference count the struct with a kref and free it fromsteelseries_device_release(). Register and unregister the power supplyexplicitly, and clear sd->battery under sd->lock in remove() so it isnot touched after it is unregistered.Drop the global atomic battery counter and name the power supply afterthe device (hdev->uniq, or dev_name() when empty), as hid-input and theother HID battery drivers do.No functional change for the current single-interface devices.Signed-off-by: Sriman Achanta Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-steelseries-arctis.c

Mon, 03 Aug 2026 21:15:50 +0200

HID: steelseries: Correct Arctis 9 battery calibration rangeMap the Arctis 9 raw battery value over 0x64 (empty) to 0x9a (full)instead of 0x68 to 0x9d. These values match the HeadsetControl project[1] and fit the calibration points from an independent reverseengineering of the battery tray (about 25% at raw 112, 50% at raw 125)[2].I do not have this headset. The values come from those references andwere not measured directly.[1] https://github.com/Sapd/HeadsetControl/blob/master/lib/devices/steelseries_arctis_9.hpp[2] https://magnier.io/reverse-engineering-arctis-9-battery-tray/Signed-off-by: Sriman Achanta Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-steelseries-arctis.c

Mon, 03 Aug 2026 21:15:49 +0200

HID: steelseries: Report POWER_SUPPLY_STATUS_FULL when fullReport POWER_SUPPLY_STATUS_FULL when the headset is connected, charging,and at 100% capacity. It reported CHARGING in that case before.The charging flag doubles as a power-present signal: the headset keepsreporting charging while it sits docked at 100%, and clears the flag assoon as it runs on battery. Gating FULL on the charging flag thereforeavoids reporting FULL for an unplugged headset that merely happens to beat 100%, which would otherwise hide the discharge state from userspace.Signed-off-by: Sriman Achanta Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-steelseries-arctis.c

49ef6ed1bbe25cf591af60c2b71cc2a65e07ea68 - HID: steelseries: Refactor Arctis driver to use device_info framework

Mon, 03 Aug 2026 21:15:48 +0200

HID: steelseries: Refactor Arctis driver to use device_info frameworkReplace the per-product if/else quirk bitmap with asteelseries_device_info struct. Each model provides its capabilities,sync_interface, and request_status/parse_status callbacks. Reportsending is folded into steelseries_send_report() and the feature andoutput wrappers, and the battery identifiers lose their per-model names.This is mostly a refactor, but it changes two things: - Battery status is polled from a periodic delayed work (status_work) instead of being requested from raw_event(). The interval stays at 3s. - Arctis 1 no longer clamps the reported capacity to 100% while disconnected. The connection state already controls how this is shown to userspace.ARCTIS_1_X and ARCTIS_9 keep working. No new devices are added.Signed-off-by: Sriman Achanta Signed-off-by: Jiri Kosina List of files: /linux/drivers/hid/hid-steelseries-arctis.c
