[patch 22/31] BusLogic gcc 4.1 warning fixes

[akpm@xxxxxxxx]

From: Daniel Walker <dwalker@xxxxxxxxxx>

- Reworked all the very long lines in that block (this drivers full of
  them though)

- Returns an error in three places that it didn't before.

- Properly clean up after a scsi_add_host() failure.
