2012-10-01[media] s5p-fimc: Don't allocate fimc-m2m video device dynamicallySylwester Nawrocki
There is no need to to dynamically allocate struct video_device for the M2M devices, so embed it instead in driver's private data structure as it is done in case of fimc-capture and fimc-lite, where it solves some bugs on cleanup paths.

2012-09-27[media] Support for Asus MyCinema U3100Mini PlusOliver Schinagl
This is initial support for the Asus MyCinema U3100Mini Plus. The driver in its current form gets detected and loads properly. Scanning using dvbscan works without problems, Locking onto a channel using tzap also works fine. Only playback using tzap -r + mplayer was tested and was fully functional. It uses the af9035 USB Bridge chip, with an af9033 demodulator. The tuner used is the FCI FC2580.
