There is a difference.  I can pay a code monkey to write clean code.
Can you pay somebody to make the driver work?
Obviously you still can not read state diagrams even after I invited you
to IRC and walked you through the documents and explaining how there are
different events described in each.  I then explain the difference of how
there are two ways to enter each one.

Then you tell me you have a grand idea for a unified interrupt handler,
which guesses what the operation to be completed by reading the command
register.  But it is only command on a write, it is status on a read,
since an interrupt happened the command opcode is gone.  NICE.

Then you toss out the next one.  Gee, I can stall device interrupts to the
interface if a toggle the eIEN line on and off.  Now where you planning to
do this between DMA interrupts if you had more than one PRD?  I never
dreamed of such a brilliant idea, but you forgot one thing.  NO touching
the taskfile registers until you stop DMAing.  Either abort the
transaction of deadlock the interface.

Now I will go learn proper C, and you have all the time you need to try
get the data-transport layer right.

As for that patch I sent you, it works but you did not try.  See after I
sent it to you on a short test compile, I ran tests on it the next day.

Lastly, I started to make a new one, but since there is no way to
determine what the entry mode of the driver upon command block execution.
