Merge tag 'rust-i2c-for-7.3' into i2c/i2cgrafted
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. Signed-off-by: Igor Korotin <igor.korotin@linux.dev> * tag 'rust-i2c-for-7.3': i2c: rust: mark I2cAdapter methods as inline

+Date: February 2006

+Description:
+ The /sys/devices tree contains a snapshot of the
+ internal state of the kernel device tree. Devices will
+ be added and removed dynamically as the machine runs,
+ and between different kernel versions, the layout of the
+ devices within this tree will change.
+
+ Please do not rely on the format of this tree because of
+ this. If a program wishes to find different things in
+ the tree, please use the /sys/class structure and rely
+ on the symlinks there to point to the proper location
+ within the /sys/devices tree of the individual devices.
+ Or rely on the uevent messages to notify programs of
+ devices being added and removed from this tree to find
+ the location of those devices.
+
+ Note that sometimes not all devices along the directory
+ chain will have emitted uevent messages, so userspace
+ programs must be able to handle such occurrences.
