Subject: [PATCH v2 0/2] rust: pwm: Fix init error handling and tidy style

This series contains two small updates to the Rust PWM bindings.

The first patch fixes a potential memory leak on an error path during PWM
chip initialization. Someone needs to decide if this goes to stable.

The second patch is just style-only cleanup.
