Subject: [PATCH] drm/tegra: submit: No need for Null pointer check before
 kfree
Message-ID: <Y6sn7XptKyk5cbrA@qemulion>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

kfree() & vfree() internally perform NULL check on the pointer handed
to it and take no action if it indeed is NULL. Hence there is no need
for a pre-check of the memory pointer before handing it to
kfree()/vfree().

Issue reported by ifnullfree.cocci Coccinelle semantic patch script.
