   -  Simplify soft key handling

  ideapad-laptop:
   -  Add E42-80 to no_hw_rfkill
   -  Add fn-lock setting
   -  Add MIIX 720-12IKB to no_hw_rfkill

  lib/string_helpers:
   -  Add missed declaration of struct task_struct

  intel_scu_ipc:
   -  Replace mdelay with usleep_range in intel_scu_ipc_i2c_cntrl

  mlx-platform:
   -  Add LED platform driver activation

  platform/mellanox:
   -  Add new ODM system types to mlx-platform
   -  mlxreg-hotplug: add extra cycle for hotplug work queue
   -  mlxreg-hotplug: Document fixes for hotplug private data

  platform_data/mlxreg:
   -  Document fixes for hotplug device

  silead_dmi:
   -  Add entry for Chuwi Hi8 tablet touchscreen
   -  Add touchscreen info for the Onda V891w tablet
   -  Add info for the PoV mobii TAB-P800W (v2.0)
   -  Add touchscreen info for the Jumper EZpad 6 Pro

  thinkpad_acpi:
   -  silence false-positive-prone pr_warn
