If no signal or valid format is detected, then VIDIOC_QUERY_DV_PRESET must
return 0 and set the preset to V4L2_DV_INVALID.
This driver returned an error instead.
Also simplified the kernel messages a bit: change v4l2_err to v4l2_dbg (not
detecting a signal/valid format is not an error, so only print this info when
debug == 1) and do not call v4l_fill_dv_preset_info: it's overkill to do this
just for a debug message.
Thanks to Mats Randgaard for bringing this to my attention.

v4l2_prio_init/open/close returned an int when in fact they would
always return 0. Make these void functions.
v4l2_prio_close and v4l2_prio_check pass an enum v4l2_priority as a
pointer for no good reason. Replace with a normal enum v4l2_priority
argument.
These changes will simplify the work of moving priority handling into
the v4l core.

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.

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.
