Subject: [PATCH v2 10/17] mdio_bus: Fix documentation for mdio_bus_match()
Date: Tue, 9 Oct 2018 10:37:58 -0700 [thread overview]
Message-ID: <20181009173805.26181-11-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181009173805.26181-1-andrew.smirnov@gmail.com>
Fix documentation for mdio_bus_match(), while at it re-arrange the
code to be easier to follow. Seeing != used as a result of a matching
function is extremely confusing.
