[PATCH v2] Input: atkbd - skip deactivate for HONOR ZQC-P

[PATCH v2] Input: atkbd - skip deactivate for HONOR ZQC-P

[Donglin Lyu]

The internal keyboard on the HONOR ZQC-P (HONOR MagicBook Pro 14 2026) 
does not work after boot.

Using the kernel command line 'i8042.dumbkbd=1' makes the keyboard 
functional, but the CapsLock LED does not work. Adding the 
'atkbd_deactivate_fixup' quirk fixes the keyboard and CapsLock LED
natively without requiring boot parameters.

DMI: HONOR ZQC-P/ZQC-P-PCB, BIOS 1.09 03/19/2026

Fixes: 9cf6e24c9fbf ("Input: atkbd - do not skip atkbd_deactivate() when skipping ATKBD_CMD_GETID")

Confirmed on a second, independently sourced ZQC-P unit. Same DMI as
yours, down to the BIOS revision:

  sys_vendor    HONOR
  product_name  ZQC-P
  board_name    ZQC-P-PCB
  bios_version  1.09
  bios_date     03/19/2026

Applied on top of 7.1.5 and booted with no i8042 parameters at all. The
keyboard works, no repeats and no dropped keys, and the Caps Lock LED
works again. The observable difference is that the keyboard input device
gains EV_LED:

  without the quirk, booted with i8042.dumbkbd=1
    B: EV=100013
    H: Handlers=sysrq kbd event2
    no LED class devices

  with the quirk, booted with no i8042 parameters
    B: EV=120013
    H: Handlers=sysrq kbd leds event2
    /sys/class/leds/input2::capslock
    /sys/class/leds/input2::numlock
    /sys/class/leds/input2::scrolllock

Nothing else on the machine changed: the I2C HID touchpad and
touchscreen, HDA and SOF audio, and the platform WMI hotkeys all behave
exactly as before.

Worth noting for the record that atkbd_dmi_quirk_table already carries
HONOR FMB-P and HONOR BCC-N, so ZQC-P is the third machine of the same
family needing this.

Applied, thank you (but rearranged entries to keep HONOR entries
together).
