Subject: media: i2c: adv7842: drop check because i2c_unregister_device() is NULL safe
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b5654c9425157706b86bdddb10b3532d09ff72e2;p=linux.git

media: i2c: adv7842: drop check because i2c_unregister_device() is NULL safe

No need to check the argument of i2c_unregister_device() because the
function itself does it.
