Season's greetings everyone,

a little present from Revolution Pi labs (https://revolution.kunbus.com/):

Two fixes and three cleanups for the Raspberry Pi DMA driver.  One of the
fixes is specific to RT but should nevertheless go into mainline (because
the issue occurs there as well if "threadirqs" is passed on the command
line).  Both fixes are marked for stable.

Thanks,

Lukas
