svn commit: r346412 - head/sys/conf

[Conrad Meyer]

Author: cem
Date: Fri Apr 19 20:08:45 2019
New Revision: 346412
URL: https://svnweb.freebsd.org/changeset/base/346412

Log:
  kernel build: Disable unhelpful GCC warning (tripped after r346352)
  
  -Wformat-zero-length does not highlight any particularly wrong code and it
  is especially meaningless for device_printf().  Turn it off entirely to
  remove a source of false positives.
