Author: andreast Date: Fri Mar 6 21:32:42 2020 New Revision: 358723 URL: https://svnweb.freebsd.org/changeset/base/358723
Log: Drop 'All rights reserved' Replace hardcoded sizes by nitems and sizeof Replace CTLFLAG_NEEDGIANT with CTLFLAG_MPSAFE, I run this driver since a few years with CTLFLAG_MPSAFE w/o issues. Add a HACK to handle a special case for a sensor location.
