Well, those abilities are at a minimum certainly goalposts and should be preferred over most everything else.

That's a relatively unusual style.
The more common style is to keep the pointer on the same line as the return type like:
static inline struct omap_desc * to_omap_dma_desc(struct dma_async_tx_descriptor *t)
It's roughly 50:1 for the * on the 1st line.

spacing, there's an 8 char space where there could be a tab.
