Jack Doan April 24, 2022, 5:14 a.m. UTC
Extend aquacomputer_d5next driver to expose hardware
temperature sensors of the Aquacomputer Farbwerk RGB controller, which
communicates through a proprietary USB HID protocol.

Four temperature sensors are available. Additionally, serial number and
firmware version are exposed through debugfs.

Also, add Jack Doan to MAINTAINERS for this driver.

Changes in v2:
  - update Kconfig so it applies cleanly
  - add "select CRC16" to Kconfig
