From: RaviChandra Sadineni <ravisadineni@xxxxxxxxxx> hi Merek, Unfortunately I could not get the device to boot even after using the exynos_defconfig. Can you please try this patch and see if this fixes the issue. If not can you enable the debug logs and send me the logs. Currently on every resume we check for mkbp events and notify the clients. This helps in identifying the wakeup sources. But on devices that do not support mkbp protocol, we might end up getting key state of the keyboard in a loop and block the resume. Instead check for events only if mkbp is supported.
