Subject: [PATCH] of: property: Fix documentation for out values
Message-ID: <20191112081726.GA8291@localhost.localdomain>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/1.12.1 (2019-06-15)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Property fetching functions which return number of successfully fetched
properties should not state that out-values are only modified if 0 is
returned. Fix this.
