Didn't we already go through this discussion once?

Here is the old thread: http://marc.info/?t=131122111000001&r=2&w=2

The chan_id is really only a sysfs detail, and for the same reasons
that scsi_host adapters don't pick their own host number neither
should dma channels.

The driver can set a channel id in its private channel struct right?
