I made one more patchset, these three functions now look consistent:
 dediprog_bulk_read_poll
 dediprog_read
 dediprog_write
For some reason I thought I can only use tabs, no spaces! With spaces it looks better.

There are 5 other occurrences where a function call (not declaration) gets too long and arguments list needs to be split, which introduces extra line. But all those 5 places are returned back in the next patch, after removing prefix extra line not needed anymore.
