Subject: [PATCH v2 06/17] smiapp: Remove unnecessary BUG_ON()'s
Date: Thu, 15 Sep 2016 14:22:20 +0300	[thread overview]
Message-ID: <1473938551-14503-7-git-send-email-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <1473938551-14503-1-git-send-email-sakari.ailus@linux.intel.com>

Instead, calculate how much is needed and then allocate the memory
dynamically.
