2014-07-04[media] videobuf2-dma-contig: allow to vmap contiguous dma buffersPhilipp Zabel
This allows drivers to vmap contiguous dma buffers so they can inspect the buffer contents with the CPU. This will be needed for the CODA driver's JPEG handling. On CODA960, the header parsing has to be done on the CPU. The hardware modules can only process the entropy coded segment after all registers and tables are set up.

2014-07-04[media] sn9c102: remove deprecated driverHans Verkuil
During the media summit meeting in Edinburgh it was decided to move this driver to staging as the first step to removing it altogether. Most webcams covered by this driver are now supported by gspca. Nobody has the hardware or is willing to convert the remaining devices to gspca. This driver needs a major overhaul to have it conform to the latest frameworks and compliancy tests. Without hardware, however, this is next to impossible. Given the fact that this driver seems to be pretty much unused (it has been removed from Fedora several versions ago and nobody complained about that), we decided to drop this driver.
