- Merge lsi64854.c rev. 1.25 from NetBSD: nuke trailing whitespace. - Update NetBSD RCS IDs according to what was actually already merged. - Remove dv_name from the lsi64854_softc and use device_printf() instead. - Use __func__ instead of hardcoded function names in error messages. - Use ulmin() instead of min() for comparing the DMA sizes as the values involved actually are represented by 64bit unsigned instead of 32bit unsigned. As far as I can't tell this doesn't make a difference in practice though. - Some style(9) fixes (mainly indentation). - Remove unnecessary braces.
