If we take an ahci driver as an example.In ahci_platform.c there are some driver functions described under:
static struct platform_driver ahci_driver = {...functions...}. The question is:What's the difference between functions described under platform_driver structure and functions described under *_ops (ahci_ops as an example)?
From my understanding, functions in the platform_driver structure are usually called automatically when loading/unloading the driver as an example. Functions described in *_ops are more user-accessible functions. Is that correct?
