* V4L/DVB: v4l: add new subdev vbi ops to handle raw and sliced vbiHans Verkuil2010-05-191-0/+9
| | | | | | | | | | | | | | Currently raw and sliced vbi is setup using the video g/s_fmt ops. However, we want to split off the vbi formatting into separate ops so the first step is to create those new ops. The next step will be to convert subdev drivers and bridge drivers to use the new ops. And in the final step we can start converting the video g/s_fmt ops to the new (and more appropriate) mediabus format ops.

* V4L/DVB: Add a new ERROR flag for DQBUF after recoverable streaming errorsPawel Osciak2010-05-191-0/+2
| | | | | | | | | | | | | | | | | | This flag is intended to indicate streaming errors, which might have resulted in corrupted video data in the buffer, but the buffer can still be reused and streaming may continue. Setting this flag and returning 0 is different from returning EIO. The latter should now indicate more serious (unrecoverable) errors. This patch also solves a problem with the ioctl handling code in vl42-ioctl.c, which does not copy buffer identification data back to the userspace when EIO is returned, so there is no way for applications to discover on which buffer the operation failed in such cases.

* V4L/DVB: cx88: fix setting input when using DVBIstvan Varga2010-05-191-1/+10
| | | | | | | | | | | | | | | In cx88-mpeg.c, there is code that sets core->input to CX88_VMUX_DVB. However, this may be incorrect, since core->input is actually an index to core->board.input[], which has not enough elements to be indexed by the value of CX88_VMUX_DVB. So, the modified code searches core->board.input[] for an input with a type of CX88_VMUX_DVB, and if it does not find one, the index is simply set to zero. The change may not have much effect, though, since it appears the only case when core->input is actually used is when the current input is being queried.

The imon-no-pad-stabilize pseudo-protocol was dropped as a protocol, and converted to a separate modprobe option (which it probably should have been in the first place). On the TODO list is to convert this to an as yet unwritten protocol-specific options framework. While the mce remotes obviously map to IR_TYPE_RC6, I've yet to look at what the actual ir signals from the native imon remotes are, so for the moment, imon native ir is mapped to IR_TYPE_OTHER.
