Subject: [PATCH 0/4] media: davinci: vpif: fix use-after-free on driver unbind

When scanning the tree for drivers that did not handle platform-device
registration failures properly I stumbled upon this driver, which also
failed to deregister device structures before freeing them.

Included are also some related runtime PM imbalance fixes and a printk
clean up.
