It was an old patch I hadn't yet reformatted to 75 cols. I used 50-60 
cols before, because my mail client's preview panel is very narrow, so 
anything more than ~65 characters will wrap. If there will be a v5, I'll 
reformat it to 75 cols as well, as per the style guidelines.

It is a general refactor patch, it shouldn't change any functionality. I 
could split it to one part introducing `devm_clk_get_enabled()` and the 
other `dmaenginem_async_device_register()`, but I don't feel that to be 
necessary, nor does it bring any advantages I believe.
