For better readability and maintenance: use the BIT() macro for flag
definitions.
NAK.  BIT() is the stupidest macro in the kernel and shall not be used
ever.  And I'm pretty sure we had this discussion a few times.
Care to explain why it is a stupid macro?
Please look at the previous thread.  I'm tired of this discussion.
The only previous answer from Christoph is this:

Yep, found that one, too.

Now, as these definitions do not correspond to hardware register bits,
perhaps use an enum?
