2008-10-17V4L/DVB (9223): MFE: Fix a number of bugs and some tidying upDarron Broad
A number of reference to videobuf_dvb_get_frontend used an invalid index. This has been fixed. The section for the HVR3000 in advise_acquire was redundant as the same logic is used on the HVR4000. This has been removed and both cards now use the same function. A number of small errors and whitespace errors are also fixed.

2008-10-17V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support.Steven Toth
A detailed description from the original patches 2 years ago: "The WinTV-HVR3000 has a single transport bus which is shared between a DVB-T and DVB-S modulator. These patches build on the bus acquisition cx88 work from a few weeks ago to add support for this. So to applications the HVR3000 looks like this: /dev/dvb/adapter0/fe0 (cx24123 DVB-S demod) /dev/dvb/adapter0/fe1 (cx22702 DVB-T demod) Additional boards continue as before, eg: /dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod) The basic change is removing the single instance of the videobuf_dvb in cx8802_dev and saa7134_dev(?) and replacing it with a list and some supporting functions. *NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so two or three current cx88 patches appear to be reversed by this tree, this will be cleaned up in the near future. The patches missing change the mutex handing to core->lock, fix an enumeration problem." It should be recognised that a number of people have been maintaining this patchset. Significant levels of Kudos to everyone one involved, including but not limited to: Darron Broad Fabio M. Di Nitto Carlo Scarfoglio Hans Werner Without the work of these people, and countless others, my two year old patches would of died on the Mercurial linuxtv.org vine a long time ago. TODO: Revise these patches a little further so that the need for demux1 and dvr0 is optional, not mandatory on the HVR3000. HISTORY (darron): This is the last update to MFE prepared by Hans which is based upon the `scratchpad' diff created by Carlo. All MFE work prior to that point must be attributed to Fabio who ported and maintained Steve's original patch up to that time.

2008-10-17V4L/DVB (9218): si470x: removement of get/set input/audioTobias Lorenz
This patch removes the unnecessary get/set input/audio functions. The reason is, that the V4L2 specification says, that if input or audio cannot be switched anyway, the functions doesn't need to be implemented. I've tested the new driver with all current radio programs in Debian/testing and found no problems with that. In my opinion, the driver is much cleaner by removing these unnecessary functions.

2008-10-17V4L/DVB (9216): si470x: tuner->type handlingTobias Lorenz

2008-10-17V4L/DVB (9215): si470x: improvement of unsupported base controlsTobias Lorenz
This patch changes the handling of unsupported base controls. In the former version, specific unsupported base controls were listed in the queryctrl table and were flagged as disabled controls. This was done for all base controls used by the applications. The patch now removes the specific base controls and instead lets queryctrl automatically return unsupported base controls flagged as disabled.

2008-10-17V4L/DVB (9214): si470x: improvement of module device supportTobias Lorenz
This patch improves support for multiple radio devices. In previous versions all region relevant settings were derived from one module parameter. As in future versions, the region and other configuration should be configurable per device from the user space, this patch already retrieves all relevant information from the actual device specific settings.

2008-10-17V4L/DVB (9213): si470x: module_param access rightsTobias Lorenz

2008-10-17V4L/DVB (9193): stk-webcam: minor cleanupDavid Ellingsworth
This patch: 1) removes the unnecessary kref.h include file 2) removes unnecessary pointer validation from read and poll routines. (Neither poll nor read may be called unless a call to open succeeds. A successful call to open will always set the file private_data pointer. Verifying that it is not null is therefore unnecessary. The associated release and mmap calls currently ignore this check.) 3) adds a space to syslog output. 4) removes an unused function prototype.
