This is a note to let you know that I've just added the patch titled gpiolib: acpi: Add quirk to ignore EC wakeups on Dell Venue 10 Pro 5055 to the 5.12-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: gpiolib-acpi-add-quirk-to-ignore-ec-wakeups-on-dell-.patch and it can be found in the queue-5.12 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f6b790510d16dfe73943d4e7b8ff4c15e3502046 Author: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Thu Apr 1 18:27:40 2021 +0200 gpiolib: acpi: Add quirk to ignore EC wakeups on Dell Venue 10 Pro 5055 [ Upstream commit da91ece226729c76f60708efc275ebd4716ad089 ] Like some other Bay and Cherry Trail SoC based devices the Dell Venue 10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to report events instead of using the standard ACPI EC interface for this. The EC interrupt is only used to report battery-level changes and it keeps doing this while the system is suspended, causing the system to not stay suspended. Add an ignore-wake quirk for the GPIO pin used by the EC to fix the spurious wakeups from suspend.
