New Revision: 355316
URL: https://svnweb.freebsd.org/changeset/base/355316

Log:
  syscons.c: clang-format pass to reduce style inconsistencies
  
  This was purely automatically massaged... some parts are still imperfect,
  but this is close enough to make it more readable/easy to work on.
  Unfortunately the vt/syscons/kdb situation slightly complicates changes to
  tty locking, so some work will need to be done to remediate that.
