[PATCH 1/2] [RESEND] media: v4l2-mem2mem: allow device run without buf

[Hsia-Jun Li <randy.li@synaptics.com>]

From: Randy Li <ayaka@soulik.info>

For the decoder supports Dynamic Resolution Change,
we don't need to allocate any CAPTURE or graphics buffer
for them at inital CAPTURE setup step.

We need to make the device run or we can't get those
metadata.
