[media] media/rc: Send sync space information on the lirc device

Userspace expects to see a long space before the first pulse is sent on
the lirc device.  Currently, if a long time has passed and a new packet
is started, the lirc codec just returns and doesn't send anything.  This
makes lircd ignore many perfectly valid signals unless they are sent in
quick sucession.  When a reset event is delivered, we cannot know
anything about the duration of the space.  But it should be safe to
assume it has been a long time and we just set the duration to maximum.

This code is needlessly complicated and checkpatch.pl complains that we
go over the 80 characters per line limit.

If we flip the "if (!lock) {" test to "if (lock) return;" then we can
remove an indent level from the rest of the function.

We can add two returns in the "if (state->srate >= 10000000) {"
condition and move the else statement back an additional indent level.

There is another "if (!lock) {" check which can be removed since we have
already checked "lock" and know it is zero at this point.  This second
check on "lock" is also a problem because it sets off a static checker

else was intended, but have concluded that it was simply an oversight

[media] cx88: convert to vb2

isn't possible. And since this affects blackbird, alsa, core, dvb, vbi and
video the changes are all over.

What made this more difficult was the peculiar way the risc program was setup.
The driver allowed for running out of buffers in which case the DMA would stop
and restart when the next buffer was queued. There was also a complicated
timeout system for when buffers weren't filled. This was replaced by a much
simpler scheme where there is always one buffer around and the DMA will just
cycle that buffer until a new buffer is queued. In that case the previous
buffer will be chained to the new buffer. An interrupt is generated at the
start of the new buffer telling the driver that the previous buffer can be
passed on to userspace.

10 years ago[media] af9005: fix kernel panic on init if compiled without IR
Frank Schaefer [Mon, 29 Sep 2014 18:17:35 +0000 (15:17 -0300)]
[media] af9005: fix kernel panic on init if compiled without IR

This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350
https://lkml.org/lkml/2014/9/18/558

If the driver is compiled in without any IR support (neither
DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in
af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.

This leads to the following oops:

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).

Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.

The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.

Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.
