  SVN rev 213526 on 2010-10-07 18:00:55Z by jh
  
  Check the device name validity on device registration.
  
  A new function prep_devname() sanitizes a device name by removing
  leading and redundant sequential slashes. The function returns an error
  for names which already exist or are considered invalid.
  
  A new flag MAKEDEV_CHECKNAME for make_dev_p(9) and make_dev_credf(9)
  indicates that the caller is prepared to handle an error related to the
  device name. An invalid name triggers a panic if the flag is not
  specified.
  
  Document the MAKEDEV_CHECKNAME flag in the make_dev(9) manual page.
