Message-ID: <1449176942-3441-2-git-send-email-subhransu.s.prusty@intel.com> (raw)
In-Reply-To: <1449176942-3441-1-git-send-email-subhransu.s.prusty@intel.com>

It is possible that some pin widget may return with no converter
connected. So don't throw error if none are found to be connected.
Instead print a warning and continue.
