Subject: [PATCH v2 0/7] platform/surface: aggregator: Extend user-space interface for events

Extend the user-space debug interface so that it can be used to receive
SSAM events in user-space.

Version 1 and rationale:
  https://lore.kernel.org/platform-driver-x86/20210603234526.2503590-1-luzmaximilian@gmail.com/

Changes in version 2:
 - PATCH 2/7: Avoid code duplication, remove unused variable
 - PATCH 4/7: Add missing mutex_destroy() calls

Maximilian Luz (7):
  platform/surface: aggregator: Allow registering notifiers without
    enabling events
  platform/surface: aggregator: Allow enabling of events without
    notifiers
  platform/surface: aggregator: Update copyright
  platform/surface: aggregator_cdev: Add support for forwarding events
    to user-space
  platform/surface: aggregator_cdev: Allow enabling of events from
    user-space
  platform/surface: aggregator_cdev: Add lockdep support
