Nit: fifo -> FIFO, tegra -> Tegra, but other than that:

A quick note on why I'm pointing out these capitalization issues so
pedantically: specifically in the "tegra" case, it's difficult to grep
for it because it matches things like "integration", which is a
surprisingly common word in the kernel. Spelling it "Tegra" consistently
make it easier to grep for Tegra related bits specifically.
