media: dvb-frontends/cxd2841er: do sleep on delivery system change
Discovered using w_scan when scanning DVB-T/T2: When w_scan goes from -T
to -T2, it does so without stopping the frontend using .sleep. Due to
this, the demod operation mode isn't re-setup, but as it still is in
STATE_ACTIVE_TC, PLP and T2 Profile are set up, but only retune_active()
is called, leaving the demod in T mode, thus not operable on any T2
frequency.
Fix this by putting the demod to sleep if priv->system isn't equal to
p->delsys. To properly accomplish this, sleep_tc() is split into
sleep_tc() and shutdown_tc(), where sleep_tc() will only perform the
sleep operation, while shutdown_tc() additionally performs the full
demod shutdown (to keep the behaviour when the .sleep FE_OP is called).

media: media/dvb: earth-pt3: fix hang-up in a rare case
When a user starts and stops filtering at a demux device too quickly
in a very short interval, the user process hangs in uninterruptible sleep,
due to an inconsistency of kthread status in the driver.
The kthread can be stopped before it starts running its thread function,
but the invocation status was partly managed in the kthread function,
which resulted in a double kthread_stop() of one kthread.

If an encoder stop command is issued after the output queue has already
stopped streaming, the qsequence counter has been reset to 0. Always
wake up the capture queue if the output queue is not streaming.

This fixes visual artifacts in the first macroblock row of encoded
MPEG-4 video output caused by 8 additional lines of luma data leaking
into the chroma planes of the internal reference framebuffers: the
buffer size is rounded up to a multiple of 16x16 macroblock size, same
as for the h.264 encoder.

CodaDx6 only accepts GOP sizes up to 60 frames, but CODA960 can handle

When CONFIG_V4L2 is built as a loadable module, the new video mux driver
fails to link as built-in code:
drivers/media/platform/video-mux.o: In function `video_mux_remove':
video-mux.c:(.text+0x24): undefined reference to `v4l2_async_unregister_subdev'
drivers/media/platform/video-mux.o: In function `video_mux_probe':

video-mux.c:(.text+0xa10): undefined reference to `v4l2_async_register_subdev'
This makes it use the same Kconfig dependency as all the other users of
the VIDEO_V4L2_SUBDEV_API symbol.
