Subject: [Patch 09/13] media: am437x-vpfe: fix function trace debug log
Date:   Mon, 9 Sep 2019 11:27:39 -0500
Message-ID: <20190909162743.30114-10-bparrot@ti.com>

Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

checkpatch.pl nows reports several:
WARNING: Prefer using '"%s...", __func__' to using '<function name>',
this function's name, in a string

So fix these for the whole driver.
