Subject: [PATCH] gpiolib: acpi: Add quirk for Dell Precision 7780
Date: Fri, 5 Dec 2025 22:32:42 +0000 [thread overview]
Message-ID: <20251205230724.2374682-1-safinaskar@gmail.com> (raw)
Dell Precision 7780 often wakes up on its own from suspend. Sometimes
wake up happens immediately (i. e. within 7 seconds), sometimes it happens
after, say, 30 minutes.
Fixes: 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
Reported-by: Askar Safin <safinaskar@zohomail.com>
