In cx88-mpeg.c, there is code that sets core->input to CX88_VMUX_DVB.
However, this may be incorrect, since core->input is actually an
index to core->board.input[], which has not enough elements to be
indexed by the value of CX88_VMUX_DVB. So, the modified code searches
core->board.input[] for an input with a type of CX88_VMUX_DVB, and if
it does not find one, the index is simply set to zero.
The change may not have much effect, though, since it appears the only
case when core->input is actually used is when the current input is
being queried.

Simplified from version 1, in that hacks heisted from ati_remote2.c
aren't actually necessary, the real fix for too many repeats was
from setting too long a timer release value (200ms) on repeats in
mce mode -- this patch drops the release timeout to 33ms, matching
the input subsystem default input_dev->rep[REP_PERIOD].

This is a follow-up to my prior patch implementing ir-core's
change_protocol functionality in the imon driver, which eliminates
a false warning when change_protocol is called without a specific
protocol selected yet (i.e., still IR_TYPE_UNKNOWN). It also removes
some extraneous blank lines getting spewn into dmesg.

Pulse-distance is not a protocol, it is a line coding (used by some protocols,
like NEC). Looking at the uses of IR_TYPE_PD, the real protocol seems to be
NEC in all cases (drivers/media/video/cx88/cx88-input.c is the only user).

So, remove IR_TYPE_PD while it is still easy to do so.

Drop the imon driver's internal protocol definitions in favor of using
those provided by ir-core. Should make ir-keytable Just Work for
switching protocol on the fly on the imon devices that support both the
native imon remotes and mce remotes.

The imon-no-pad-stabilize pseudo-protocol was dropped as a protocol, and
converted to a separate modprobe option (which it probably should have
been in the first place). On the TODO list is to convert this to an as yet
unwritten protocol-specific options framework.

While the mce remotes obviously map to IR_TYPE_RC6, I've yet to look at
what the actual ir signals from the native imon remotes are, so for the
moment, imon native ir is mapped to IR_TYPE_OTHER. Nailing it down more
accurately is also on the TODO list.

The values for the fourcc format were correct, but applied to the
wrong register. With this change, video is now barely working again with
tm6000.

While here, let's remove, for now, the memset. This way, people can
have some image when testing this device.

Yet to be fixed: parts of the image frame are missed. As we don't clean
the buffers anymore, this is "recovered" by repeating the values from a
previous frame. The quality is bad, since the image pixels will contain
data from some previous frames, generating weird delay artifacts.

Changing a video standard takes a long time to happen on tm6000, since it
needs to load another firmware, and the i2c implementation on this device
is really slow. When the driver tries to change the video standard, a
kernel panic is produced:

BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
IP: [<ffffffffa0c7b48a>] tm6000_irq_callback+0x57f/0xac2 [tm6000]
...
Kernel panic - not syncing: Fatal exception in interrupt

By inspecting it with gdb:

(gdb) list *tm6000_irq_callback+0x57f
0x348a is in tm6000_irq_callback (drivers/staging/tm6000/tm6000-video.c:202).
197             /* FIXME: move to tm6000-isoc */
198             static int last_line = -2, start_line = -2, last_field = -2;
199
200             /* FIXME: this is the hardcoded window size
201              */
202             unsigned int linewidth = (*buf)->vb.width << 1;
203
204             if (!dev->isoc_ctl.cmd) {
205                     c = (header >> 24) & 0xff;
206

Clearly, it was the trial to access *buf, at line 202 that caused the
Panic.

As ioctl is serialized, While S_STD is handled,QBUF/DQBUF won't be called.
So, the driver will run out of the buffers, and *buf will become NULL.

As, on tm6000, the same URB can contain more than one video buffer, it is
likely to hit a condition where no new buffer is available whily copying
the streams. The fix is to leave the URB copy loop, if there's no more buffers
are available.

The same bug could also be produced by an application that is not fast enough
to request new video buffers.
