This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

After these patches are applied, the build system no longer
complains about any W=0 nor W=1 level warnings in drivers/dma.

Hurrah!

Struct attribute names must be an exact match or the kerneldoc checker
gets confused.

Fixes the following W=1 kernel build warning(s):
