You should know 80 char is a warn not an error, and you should read the
Codingstyle documentation before you embark on these changes.
The guiding principle here is readablity and greapblity, anything which
breaks these is strict NO.

This makes it harder to read, if you see drivers the will do it:
static inline struct omap_desc
*to_omap_dma_desc(struct dma_async_tx_descriptor *t)

whats changes here? title says 80 char!
