[PATCH 0/2] rust: leds: add led classdev abstractions

Posted by Markus Probst 2 months, 1 week ago

This patch series has previously been contained in
https://lore.kernel.org/rust-for-linux/20251008181027.662616-1-markus.probst@posteo.de/T/#t
which added a rust written led driver for a microcontroller via i2c.

As the reading and writing to the i2c client via the register!
macro has not been implemented yet [1], the patch series will only
contain the additional abstractions required.

[1] https://lore.kernel.org/rust-for-linux/DDDS2V0V2NVJ.16ZKXCKUA1HUV@kernel.org/

The following changes were made:
* add basic Pin<Vec<T, A>> abstractions, that allow to initialize PinInit items with
  the gurantee that these will never be moved.

* add basic led classdev abstractions to register and unregister leds

"gurantee" -> "guarantee"
