Subject: [PATCH v4 3/9] phy: ti-pipe3: move sysctrl initialization to a separate function
Date: Mon, 21 Dec 2015 14:24:07 +0530 [thread overview]
Message-ID: <1450688053-3429-4-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1450688053-3429-1-git-send-email-kishon@ti.com>
No functional change. Moved sysctrl initialization done in probe to a
separate function as part of cleaning up ti_pipe3_probe.
