Subject: [PATCH 12/12] of: overlay: remove unneeded check for NULL kbasename()
Date: Mon,  2 Oct 2017 20:53:46 -0700	[thread overview]
Message-ID: <1507002826-16393-13-git-send-email-frowand.list@gmail.com> (raw)
In-Reply-To: <1507002826-16393-1-git-send-email-frowand.list@gmail.com>

From: Frank Rowand <frank.rowand@sony.com>

kbasename() will not return NULL if passed a valid string.  If
the parameter passed to kbasename() in this case is already NULL
then the devicetree has been corrupted.
