svn commit: r191116 - head/sys/kern

[Ed Schouten]

Author: ed
Date: Wed Apr 15 20:15:36 2009
New Revision: 191116
URL: http://svn.freebsd.org/changeset/base/191116

Log:
  Remove unneeded variable and casting from newdev().
  
  Remove the `udev' variable, which has a different type than the original
  function argument and si_drv0. The `udev' name is also misleading,
  because it is not the number returned by dev2udev(). Rename this
  argument to `unit'. It is the same number as returned by dev2unit().
