Merge tag 'hid-for-linus-2026052801' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid
Pull HID fixes from Benjamin Tissoires: - buffer overflow fix for lenovo (Kean) and wacom (Lee Jones) drivers - segfaults prevention in lenovo-go driver when used with an emulated device (Louis Clinckx) - cleanup of resources in u2fzero (Myeonghun Pak) - a quirk for a USB mouse and a cleanup in hid.h (hlleng and Liu Kai) * tag 'hid-for-linus-2026052801' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid: HID: wacom: Fix OOB write in wacom_hid_set_device_mode() HID: lenovo-go: drop dead NULL check on to_usb_interface() HID: lenovo-go: reject non-USB transports in probe HID: lenovo: Fix buffer over-read and unaligned access in X12 Tab raw_event handler HID: quirks: Add ALWAYS_POLL quirk for SIGMACHIP USB mouse HID: remove duplicate hid_warn_ratelimited definition HID: u2fzero: free allocated URB on probe errors
