Subject: [PATCH] platform/x86/amd/pmc: Declare quirk_spurious_8042 for MECHREVO Wujie 14XA (GX4HRXL)
MECHREVO Wujie 14XA (GX4HRXL) wakes up immediately after s2idle entry.
This happens regardless of whether the laptop is plugged into AC power,
or whether any peripheral is plugged into the laptop.
Similar to commit a55bdad5dfd1 ("platform/x86/amd/pmc: Disable keyboard
wakeup on AMD Framework 13"), the MECHREVO Wujie 14XA wakes up almost
instantly after s2idle suspend entry (IRQ1 is the keyboard):
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 9
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 1
Add this model to the spurious_8042 quirk to workaround this.
This patch does not affect the wake-up function of the built-in keyboard.
Because the firmware of this machine adds an insurance for keyboard
wake-up events, as it always triggers an additional IRQ 9 to wake up the
system.
I have only matched the motherboard model, as the same chassis and
motherboard (GX4HRXL) combination may be used under different product
names.
