RC_TYPE_LIRC and map_name = RC_MAP_LIRC set, the driver open will be never
called. The reason for this is, all of the key maps except lirc have some
KEYS in there map, so during rc_register_device process these keys are
matched against the input drivers and open is performed, so for the case
of RC_MAP_EMPTY, a vt/keyboard is matched and the driver open is
performed.
In case of lirc, there is no match and result is that there is no open
performed, however the lirc-dev will go ahead and create a /dev/lirc0
node. Now when lircd/mode2 opens this device, no data is available
because the driver was never opened.
Other case pointed by Sean Young, As rc device gets opened via the
input interface. If the input device is never opened (e.g. embedded with
no console) then the rc open is never called and lirc will not work
either. So that's another case.
lirc_dev seems to have no link with actual rc device w.r.t open/close.
This patch adds rc_dev pointer to lirc_driver structure for cases like
this, so that it can do the open/close of the real driver in accordance
to lircd/mode2 open/close.
Without this patch its impossible to open a rc device which has

works ok if we have any input drivers to match. But in case like lirc

[media] coda: add CODA7541 decoding support

This patch enables decoding of h.264 and mpeg4 streams on CODA7541.
Queued output buffers are immediately copied into the bitstream
ringbuffer. A device_run can be scheduled whenever there is either
enough compressed bitstream data, or the CODA is in stream end mode.
Each successful device_run, data is read from the bitstream ringbuffer
and a frame is decoded into a free internal framebuffer. Depending on
reordering, a possibly previously decoded frame is marked as display
frame, and at the same time the display frame from the previous run
is copied out into a capture buffer by the rotator hardware.
The dequeued capture buffers are counted to send the EOS signal to
userspace with the last frame. When userspace sends the decoder stop
command or enqueues an empty output buffer, the stream end flag is
set to allow decoding the remaining frames in the bitstream
ringbuffer.
The enum_fmt/try_fmt functions return fixed capture buffer sizes
while the output queue is streaming, to allow better autonegotiation
in userspace.
A per-context buffer mutex is used to lock the picture run against
buffer dequeueing: if a job gets queued, then streamoff dequeues
the last buffer, and then device_run is called, bail out. For that
the interrupt handler has to be threaded.

invoked only after checking asd->bus_type. So drop redundant
checks in match_i2c() and match_platform() functions.
