svn commit: r343029 - head/sys/dev/led

[Oleksandr Tymoshenko]

Author: gonzo
Date: Tue Jan 15 00:52:41 2019
New Revision: 343029
URL: https://svnweb.freebsd.org/changeset/base/343029

Log:
  [led] propagate error from set_led() to the caller
  
  Do not lose error condition by always returning 0 from set_led.
  None of the calls to set_led checks for return value at the moment so
  none of API consumers in base is affected.
