I can make happen that the polling mode will be unconditionally
set as default.

Do you think that the interrupt mode code can still stay in the
driver, because maybe in future could be fixed?

How interrupt mode would exist in such case? Or rather: how would it be
used? There is no point to keep dead code and code once removed, can be
easily brought back.

I can make a module param i.e. irq-mode=1, while in default where
the user don't provide param, we use polling mode. Then I don't have to
remove DT interrupts and the related code from the driver.
