It’s not an equivalent. Have you tested on actual hardware? If no, there is

no go for this change.

Yep, this has been like this since the initial introduction of this driver.
Unfortunately there's no documented reason so unless we can test it, it has
to stay this way.

I tested driver, functionality wise everything working fine.
Based on below conversation, I moved driver to module driver.
