Subject: [PATCH v2] media: i2c: adv748x: Use devm to allocate the device struct
Date: Fri, 11 Jan 2019 16:17:03 +0000 [thread overview]
Message-ID: <20190111161703.7972-1-kieran.bingham+renesas@ideasonboard.com> (raw)
From: Steve Longerbeam <steve_longerbeam@mentor.com>
Switch to devm_kzalloc() when allocating the adv748x device struct.
The sizeof() is updated to determine the correct allocation size from
the dereferenced pointer type rather than hardcoding the struct type.
