Subject: [PATCH v3 15/22] mdio_bus: Fix documentation for mdio_bus_match()
Date: Sun, 14 Oct 2018 19:21:18 -0700	[thread overview]
Message-ID: <20181015022125.24020-16-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181015022125.24020-1-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.
