If anyone has any objections, please let me know. ------------------ From: Antoniu Miclaus commit 91f950b4cbb1aa9ea4eb3999f1463e8044b717fb upstream. The return value of pm_runtime_get_sync() is not checked, and the function always returns success. This allows I2C mux operations to proceed even when the device fails to resume. Use pm_runtime_resume_and_get() and propagate its return value to properly handle resume failures.
