Merge branches 'acpi-ac', 'acpi-pad' and 'pnp'

Merge updates of the ACPI AC and ACPI PAD drivers and PNP updates for
6.7-rc1:

 - Switch over the ACPI AC and ACPI PAD drivers to using the platform
   driver interface which, is more logically consistent than binding a
   driver directly to an ACPI device object, and clean them up (Michal
   Wilczynski).

 - Replace strncpy() in the PNP code with either memcpy() or strscpy()
   as appropriate (Justin Stitt).

 - Clean up coding style in pnp.h (GuoHua Cheng).

* acpi-ac:
  ACPI: AC: Rename ACPI device from device to adev
  ACPI: AC: Replace acpi_driver with platform_driver
  ACPI: AC: Use string_choices API instead of ternary operator
  ACPI: AC: Remove redundant checks

* acpi-pad:
  ACPI: acpi_pad: Rename ACPI device from device to adev
  ACPI: acpi_pad: Use dev groups for sysfs
  ACPI: acpi_pad: Replace acpi_driver with platform_driver

* pnp:
  PNP: replace deprecated strncpy() with memcpy()
  PNP: ACPI: replace deprecated strncpy() with strscpy()
  PNP: Clean up coding style in pnp.h
