coda: move per-instance buffer allocation and cleanup
This patch moves the context buffer allocation into the context start_streaming callbacks. The context buffer and internal framebuffer cleanup is moved into the context release callback. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Kamil Debski <k.debski@samsung.com>
