[PATCH 2/2] [W1] ds1wm: report bus reset error

[Anton Vorontsov]

The patch replaces dev_dbg() by dev_err(), so the user could actually
see the error, instead of wondering why w1 doesn't work. The root cause
of the bus reset error isn't yet debugged though, but this sometimes
happens on iPaq H5555.

And while I'm at it, some cosmetic cleanups also made (few lines were
using spaces instead of tabs).
