Subject: [PATCH 0/5] rust: serdev: Refactor
Date: Sun, 06 Sep 2026 15:55:25 +0000 [thread overview]
Message-ID: <20260906-rust_serdev_probe_refactor-v1-0-69cdae0074ec@posteo.de> (raw)
The following has been changed:
- introduce a new C serdev API to fix race conditions and simplify rust
code. Should also be useful on the C side.
- fix race conditions
- simplify rust code
- add rust function to provide mutable references to driver's private
data
- provide mutable references in callbacks to avoid the need for a
SpinLock in the greybus patch series [1]
