[PATCH 0/2] ACPI: PM: s2idle: Print debug messages in two new places

[Rafael J. Wysocki]

Hi All,

This series causes PM debug messages to be printed in two new places to help
diagnose issues related to wakeup from suspend-to-idle.

Thanks!

[PATCH 1/2] ACPI: PM: Print additional debug message in acpi_s2idle_wake()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Make acpi_s2idle_wake() print an additional debug message when the
SCI is going to be rearmed for system wakeup to help diagnose
wakeup-related issues.
