Pull media updates from Mauro Carvalho Chehab:

 - videobuf2 was moved to a media/common dir, as it is now used by the
   DVB subsystem too

 - Digital TV core memory mapped support interface

 - new sensor driver: ov7740

 - several improvements at ddbridge driver

 - new V4L2 driver: IPU3 CIO2 CSI-2 receiver unit, found on some Intel
   SoCs

 - new tuner driver: tda18250

 - finally got rid of all LIRC staging drivers

 - as we don't have old lirc drivers anymore, restruct the lirc device
   code

 - add support for UVC metadata

 - add a new staging driver for NVIDIA Tegra Video Decoder Engine

 - DVB kAPI headers moved to include/media

 - synchronize the kAPI and uAPI for the DVB subsystem, removing the gap
   for non-legacy APIs

 - reduce the kAPI gap for V4L2

 - lots of other driver enhancements, cleanups, etc.

* @buffer2_length: Length of the TS data in buffer2.
* @source: Indicates which TS feed is the source of the callback.
*
* This function callback prototype, provided by the client of the demux API,
* is called from the demux code. The function is only called when filtering
* on a TS feed has been enabled using the start_filtering\(\) function at
* the &dmx_demux.
* Any TS packets that match the filter settings are copied to a circular
* buffer. The filtered TS packets are delivered to the client using this
* callback function.
* It is expected that the @buffer1 and @buffer2 callback parameters point to
* addresses within the circular buffer, but other implementations are also
* possible. Note that the called party should not try to free the memory
* the @buffer1 and @buffer2 parameters point to.
*
* When this function is called, the @buffer1 parameter typically points to
* the start of the first undelivered TS packet within a circular buffer.
* The @buffer2 buffer parameter is normally NULL, except when the received
* TS packets have crossed the last address of the circular buffer and
* "wrapped" to the beginning of the buffer. In the latter case the @buffer1
* parameter would contain an address within the circular buffer, while the
* @buffer2 parameter would contain the first address of the circular buffer.
* The number of bytes delivered with this function (i.e. @buffer1_length +
* @buffer2_length) is usually equal to the value of callback_length parameter
* given in the set() function, with one exception: if a timeout occurs before
* receiving callback_length bytes of TS data, any undelivered packets are
* immediately delivered to the client by calling this function. The timeout
* duration is controlled by the set() function in the TS Feed API.
*
* If a TS packet is received with errors that could not be fixed by the
* TS-level forward error correction (FEC), the Transport_error_indicator
* flag of the TS packet header should be set. The TS packet should not be
* discarded, as the error can possibly be corrected by a higher layer
* protocol. If the called party is slow in processing the callback, it
* is possible that the circular buffer eventually fills up. If this happens,
* the demux driver should discard any TS packets received while the buffer
* is full and return -EOVERFLOW.
*
* The type of data returned to the callback can be selected by the
* &dmx_ts_feed.@set function. The type parameter decides if the raw
* TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
* should be returned. If additionally the TS_DECODER bit is set the stream
* will also be sent to the hardware MPEG decoder.
*
* Return:
*
* - 0, on success;
*
* - -EOVERFLOW, on buffer overflow.

* &dmx_ts_feed.@start_filtering. When the demux driver has received a
* complete section that matches at least one section filter, the client
* is notified via this callback function. Normally this function is called
* for each received section; however, it is also possible to deliver
* multiple sections with one callback, for example when the system load
* is high. If an error occurs while receiving a section, this
* function should be called with the corresponding error type set in the
* success field, whether or not there is data to deliver. The Section Feed
* implementation should maintain a circular buffer for received sections.
* However, this is not necessary if the Section Feed API is implemented as
* a client of the TS Feed API, because the TS Feed implementation then
* buffers the received data. The size of the circular buffer can be
* configured using the &dmx_ts_feed.@set function in the Section Feed API.

* the section must be discarded. If this happens, the value of the success

* It returns a struct list_head pointer to the list of front-end
* interfaces, or NULL in the case of an empty list.
*
* @connect_frontend: Connects the TS output of the front-end to the input of
* the demux. A demux can only be connected to a front-end registered to
* the demux with the function @add_frontend. It may or may not be
* possible to connect multiple demuxes to the same front-end, depending
