From d576a9561a1c80ae593539fb0ce0743d66825ac2 Mon Sep 17 00:00:00 2001 From: Andi Shyti Date: Sat, 22 Aug 2026 14:19:12 +0200 Subject: Merge tag 'rust-i2c-for-7.3' into i2c/i2c i2c: rust: mark I2cAdapter methods as inline A single cleanup for the Rust I2C abstractions, targeting 7.3. `I2cAdapter::get`, `inc_ref`, and `dec_ref` are trivial wrappers around `i2c_get_adapter`/`i2c_put_adapter` and were showing up as their own symbols in the build. Mark them `#[inline]` so they get folded into their callers instead.
