[PATCH v12 0/2] Lenovo Yoga Book 9 keyboard dock detection

[Dave Carey <carvsdriver@gmail.com>]

Changes in v12 (addressing Ilpo Järvinen's v11 review of patch 2/2):

  - Add #include <linux/sysfs.h> (for sysfs_emit)
  - Add #include <linux/types.h> (for __le32 and __packed)

Changes in v11 (addressing Armin Wolf's v10 review of patch 2/2):

  - ABI doc: correct Date to "June 2027" and KernelVersion to "7.3";
    these fields should reflect when the ABI lands in the kernel, not
    the submission date.

Patch 1/2 (lenovo-ymc) is unchanged from v10.

Changes in v10 (addressing Armin Wolf's v9 review of patch 2/2):

  - Update ABI doc: Date: June 2026, KernelVersion: 6.16
  - Add #include <linux/compiler_attributes.h> and <linux/types.h>
  - yb9_kbdock_query(): change return to pointer-out u32 *bkbd to avoid
    a 0xFFFFFFFF status value being misread as -EPERM
  - struct yb9_kbdock_data: add spinlock_t lock
  - yb9_kbdock_report(): hold lock across input_report_switch + input_sync
  - yb9_kbdock_sync(): return int, propagate query error to callers
  - yb9_kbdock_resume(), yb9_kbdock_block_probe(): propagate sync error
  - struct wmi_buffer out: remove zero-initializer (not needed)
  - yb9_kbdock_notify_new(): drop manual length check; use
    .min_event_size = sizeof(__le32) in struct wmi_driver instead

Patch 1/2 (lenovo-ymc) is unchanged from v9.
