Subject: [PATCH 1/2] media: i2c: adv7511-v4l2: drop check because i2c_unregister_device() is NULL safe
Date: Tue, 20 Aug 2019 17:34:40 +0200 [thread overview]
Message-ID: <20190820153441.7748-1-wsa+renesas@sang-engineering.com> (raw)
No need to check the argument of i2c_unregister_device() because the
function itself does it.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>
