[PATCH 3.12 028/111] ARM: imx: fix error handling in ipu device registration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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)
