Subject: [PATCH] ARM: ep93xx: Avoid soc_device_to_device()
Date:   Mon, 11 Nov 2019 23:37:22 +0100
Message-Id: <20191111223722.2364-1-afaerber@suse.de>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Precedence: bulk

ep93xx_init_soc() uses soc_device_to_device() to return a device
to ep93xx_init_devices(), where it is passed on to its callers,
who all ignore the return value. As this helper is deprecated,
change the return type of ep93xx_init_devices() to void and
have ep93xx_init_soc() return the soc_device instead.
