svn commit: r287356 - head/sys/dev/mmc/host

[Andrew Turner]

Author: andrew
Date: Tue Sep  1 10:47:42 2015
New Revision: 287356
URL: https://svnweb.freebsd.org/changeset/base/287356

Log:
  Remove an variable we only ever write to, and stop assigning 0 to values
  in the softc as it's the default value. The latter helps with subclassing
  this driver.
