From: Emil Goode <emilgoode@xxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit d1d70e5dc2cfa9047bb935c41ba808ebb8135696 upstream.
If we fail to allocate struct platform_device pdev we
dereference it after the goto label err.
This bug was found using coccinelle.
Fixes: afa77ef (ARM: mx3: dynamically allocate "ipu-core" devices)
