Subject: depca.c: fix handling of platorm_device_add() failure
From: Andrea Righi <a.righi@xxxxxxxxx>
Fix a bug in depca_platform_probe().
We don't use a dynamic pointer for pldev->dev.platform_data, so it seems
that the correct way to proceed if platform_device_add(pldev) fails is to
explicitly set the pldev->dev.platform_data pointer to NULL, before calling
the platform_device_put(pldev), or it will be kfree'ed by
platform_device_release().
