There was assignment of memory bank with dma address converted
from physical address. But allocation has been changed with dma
function, so the assignment is not necessary.

rmat, and usually *it is not aligned with
PAGE_SIZE* even though internal allocation is aligned. So the check
routine of size in __qbuf_dmabuf() returns failure.
I am not sure about queue_setup of UVC driver, but it seems same issue.
Maybe we can add PAGE_ALIGN for size from queue_setup in the
__
__qbuf_dmabuf checks whether size of provided dmabuf is large
enough, and it returns error without any log. So this patch adds
error log in the case.

It is hard to distinguish between decoder and encoder video device
because their names are same. So this patch fixes the names.

The v4l2_m2m_poll() does not need to wait if there is already a buffer in
done_list of source and destination queues, but current v4l2_m2m_poll() always
waits. So done_list of each queue is checked before calling poll_wait().

So I add check routine for done_list before calling poll_wait().
But I'm not sure that locking for done_lock of queue is also needed in this
case or not because done_list of queue is checked without locking in some
other parts of vb2.

The length of mmap() can be bigger than length of vb2 buffer, so
it should be checked.
