[PATCH 0/2] Introduce Synology Microp driver

[Markus Probst]

Synology uses a microcontroller in their NAS devices connected to a
serial port to control certain LEDs, fan speeds, a beeper, to handle
proper shutdown and restart, buttons and fan failures.

This patch series depends on the rust led abstraction [1] and the rust
serdev abstraction [2].

This is only a initial version of the driver able to control LEDs and thus
goes into the staging tree.

The following rust abstractions would be required, to implement the
remaining features:
- hwmon (include/linux/hwmon.h)
- input (include/linux/input.h)
- sysoff handler + hardware protection shutdown (include/linux/reboot.h)
