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().
