This series is based on linux-next, tag: next-20241105

Changes in v2:
- author name modification
- replacement of pm runtime API
- removal of redundant error messages
- return value adjustment
- add runtime pm status check

The delay before runtime_put_autosuspend() actually executes 
mtk_i2c_runtime_suspend() depends on the frequency of I2C usage by the 
devices attached to this bus. A 1000ms delay is a balanced value for 
latency and power metrics based on the MTK platform.
