2016-09-09[media] doc-rst: Correct the ordering of LSBs of the 10-bit raw packed formatsSakari Ailus
The 10-bit packed raw bayer format documented that the data of the first pixel of a four-pixel group was found in the first byte and the two highest bits of the fifth byte. This was not entirely correct. The two bits in the fifth byte are the two lowest bits. The second pixel occupies the second byte and third and fourth least significant bits and so on.

2016-09-09[media] fix broken references on dvb/video*rstMauro Carvalho Chehab
Trivially fix those broken references, by copying the structs fron the header, just like other API documentation at the DVB side. This doesn't have the level of quality used at the V4L2 side of the API, but, as this documents a deprecated API, used only by av7110 driver, it doesn't make much sense to invest time making it better.
