treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

HID: intel-thc: fix CONFIG_HID dependency

2025-02-03T09:56:43Z

In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use 'select HID'. With the newly added INTEL_THC_HID, this causes a build warning for a circular dependency: WARNING: unmet direct dependencies detected for HID Depends on [m]: HID_SUPPORT [=y] && INPUT [=m] Selected by [y]: - INTEL_THC_HID [=y] && HID_SUPPORT [=y] && X86_64 [=y] && PCI [=y] && ACPI [=y] WARNING: unmet direct dependencies detected for INPUT_FF_MEMLESS Depends on [m]: INPUT [=m] Selected by [y]: - HID_MICROSOFT [=y] && HID_SUPPORT [=y] && HID [=y] - GREENASIA_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_GREENASIA [=y] - HID_WIIMOTE [=y] && HID_SUPPORT [=y] && HID [=y] && LEDS_CLASS [=y] - ZEROPLUS_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ZEROPLUS [=y] Selected by [m]: - HID_ACRUX_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ACRUX [=m] - HID_EMS_FF [=m] && HID_SUPPORT [=y] && HID [=y] - HID_GOOGLE_STADIA_FF [=m] && HID_SUPPORT [=y] && HID [=y] - PANTHERLORD_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_PANTHERLORD [=m] It's better to be consistent and always use 'depends on HID' for HID drivers. The notable exception here is USB_KBD/USB_MOUSE, which are alternative implementations that do not depend on the HID subsystem. Do this by extending the "if HID" section below, which means that a few of the duplicate "depends on HID" and "depends on INPUT" statements can be removed in the process.

Bluetooth: Fix race condition in hidp_session_thread

2023-04-10T17:22:46Z

There is a potential race condition in hidp_session_thread that may lead to use-after-free. For instance, the timer is active while hidp_del_timer is called in hidp_session_thread(). After hidp_session_put, then 'session' will be freed, causing kernel panic when hidp_idle_timeout is running. The solution is to use del_timer_sync instead of del_timer. Here is the call trace: ? hidp_session_probe+0x780/0x780 call_timer_fn+0x2d/0x1e0 __run_timers.part.0+0x569/0x940 hidp_session_probe+0x780/0x780 call_timer_fn+0x1e0/0x1e0 ktime_get+0x5c/0xf0 lapic_next_deadline+0x2c/0x40 clockevents_program_event+0x205/0x320 run_timer_softirq+0xa9/0x1b0 __do_softirq+0x1b9/0x641 __irq_exit_rcu+0xdc/0x190 irq_exit_rcu+0xe/0x20 sysvec_apic_timer_interrupt+0xa1/0xc0 Cc: stable@vger.kernel.org Signed-off-by: Min Li Signed-off-by: Luiz Augusto von Dentz

Merge branch 'for-6.3/hid-bpf' into for-linus

2023-02-22T09:44:31Z

Initial support of HID-BPF (Benjamin Tissoires) The history is a little long for this series, as it was intended to be sent for v6.2. However some last minute issues forced us to postpone it to v6.3. Conflicts: * drivers/hid/i2c-hid/Kconfig: commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID") conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected when I2C_HID_OF_ELAN is") the resolution is simple enough: just drop the "default" and "select" lines as the new commit from Arnd is doing

HID: fix BT_HIDP Kconfig dependencies

2022-11-21T17:36:19Z

If HID_SUPPORT is not selected, BT_HIDP should not be available, simply because we disallowed the HID bus entirely. Add a new depends and actually revert this file back to where it was 10 years ago before it was changed by commit 1f41a6a99476 ("HID: Fix the generic Kconfig options").
