From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sebastian Hesselbarth Subject: [PATCH] net: mv643xx_eth: use managed devm_kzalloc Date: Wed, 10 Apr 2013 19:38:03 +0200 Message-ID: <1365615483-26318-1-git-send-email-sebastian.hesselbarth@gmail.com> Cc: Lennert Buytenhek , Andrew Lunn , Jason Cooper , Florian Fainelli , netdev@vger.kernel.org, linux-kernel@vger.kernel.org To: Sebastian Hesselbarth Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org This patch moves shared private data kzalloc to managed devm_kzalloc and cleans now unneccessary kfree and error handling. Signed-off-by: Sebastian Hesselbarth --- Note that there is also an ioremap call, that could be transferred to devm_ioremap_resource. But as long as mv643xx_eth and mvmdio iomem resources overlap, this will throw -EBUSY.
