This is a portability fix and reduces stack usage.
The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet
payload buffers in firedtv (payload of write requests in avc_write and
of lock requests in cmp_lock) to slab-allocated memory.
We use the 512 bytes sized FCP frame buffer in struct firedtv for this
purpose. Previously it held only incoming FCP responses, now it holds
pending FCP requests and is then overwriten by an FCP response from the
tuner subunit. Ditto for CMP lock requests and responses. Accesses to
the payload buffer are serialized by fdtv->avc_mutex.
As a welcome side effect, stack usage of the AV/C transaction functions
is reduced by 512 bytes.
Alas, avc_register_remote_control() is a special case: It previously
did not wait for a response. To fit better in with the other FCP
transactions, let it wait for an interim response.

This change attempts to fix the ivtv tinny audio problem by keeping digitizer
to encoder audio clocks running, while disabling the video clocks as needed to
avoid unpredictable PCI bus hangs.
To accomplish this, for the cx25840 module enabling of audio streaming had
to be separated from enabling video streaming, requiring an additional
v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers.
The cx231xx and cx23885 driver use the cx25840 module for affecting only
video on s_stream calls, so those drivers needed no change.
The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI
bus hang, so the cx18 driver did not need corresponding changes.
CX2341[56] based cards that are not using the CX2584x family of chips
do not seem to be affected by the tinny audio problem, and this change should
not affect how they are configured. It will delay their first capture by

There are several DMA related interrupts which wake up the dma_waitq. The udma

window exists between the IVTV_F_I_UDMA_PENDING flag being cleared and the

From LNBH24 datasheet:
"In order to improve design flexibility an external tone input pin is
