Subject: [PATCH 19/19] ARM: OMAP3+: SmartReflex: fix the use of debugfs_create_* API
Date: Tue, 31 Jan 2012 10:58:32 +0100 [thread overview]
Message-ID: <1328003912-11709-20-git-send-email-j-pihet@ti.com> (raw)
In-Reply-To: <1328003912-11709-1-git-send-email-j-pihet@ti.com>
The debugfs_create_* API returns a NULL ptr in case of problem.
Fix the smartreflex code to take this into account.
