[PATCH] fixup! dmaengine: pxa_dma: add debug information

Hello Robert.

The return value of that dbg_show_requester_chan function
was incorrect and the increment of pos was an example of
why the seq_printf return value was changed to void.

It was a pretty common error and easy to understand given
the expectation that seq_printf should work like printf.

Sure.

It's a pity it bit you. but this type of patch collision
should be a bit more difficult to reoccur in the future.

I got what I deserved. I knew it was coming, I've seen it in other drivers of
mine, but my left brain didn't tell the other half to crosscheck in this
patch. Anyway, it's not a big fixup, so everything is fine now.

Cheers.
