Would you have a suggestion for such a name? Something like
ufshcd_driver_release_action()?

Unless I'm misunderstanding you, I believe most drivers use
a function name that says what the function does, e.g.
dell_wmi_ddv_debugfs_remove (just as a completely random
example out of many).

If going by when it is called and if applying this principle
throughout ufshcd, then there can only ever be one such
function in ufshcd, as all devm_add_action() callback actions
happen at driver release, which surely isn't what you mean.

You probably meant something different?

Cheers,
