The driver currently takes the hardwired FIFO address from
a header file that we want to eliminate. Change it to use
the mmio resource instead and stop including the heare.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Fixed, I guess I lost an 'A' somewhere.

What is a "heare" ? I hear something like "including it here" maybe ...

Otherwise : Acked-by: Robert Jarzmik <robert.jarzmik@free.fr>
