Subject: [PATCH RFC 01/26] dmaengine: omap-dma: use devm_kzalloc() to allocate omap_dmadev.
Date: Thu, 02 Jan 2014 15:07:01 +0000	[thread overview]
Message-ID: <E1VyjrR-0004zN-P4@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20140102150621.GJ16456@n2100.arm.linux.org.uk>

Use devm_kzalloc() to allocate omap_dmadev() so that we don't need
complex error cleanup paths.
