charset=UTF-8 Content-Transfer-Encoding: 8bit V4L2 specifies the audio mode to use for combinations of possible (rxsubchans) and requested (audmode) audio modes.

It then forced the hardware to use the mode requested by the user. With this patch it continues to adjust the audio mode while taking the requested mode into account.

Such config never make much sense, and created several issues in order to make the Kconfig dependency to work, as all drivers that depend on both (most TV drivers) would need to be compiled as 'm'. Due to that, the VIDEO_MEDIA config option were added. Instead of such weird approach, let's just use the MEDIA_SUPPORT =y or =m to select if the media subsystem core will be either builtin or module, simplifying the building system logic. Also, fix the tuners configuration, by enabling them only if a tuner is required. So, if just webcam/grabbers support is selected, no tuner option will be selected. Also, if only digital TV is selected, no analog tuner support is selected. That removes the need of using EXPERT customise options, when analog TV is not selected.

This works for the URBs allocated with usb_alloc_urb(), as those are allocated from cohernent DMA pools, but the flag was also added for the VBI and audio URBs, which have a manually allocated area. This leaves the random trash in the structure after allocation as the DMA address, corrupting memory and preventing VBI and audio from working. Letting the USB core map the buffers solves the problem.

The driver shows an error in dmesg When using the 4-parameter command with firmware that implements the 2-parameter command. Unfortunately this happens every time when chaning the frequency (on DVB-C). This patch simply makes configurable, how many command parameters will be used. All existing drxk_config instances using the "drxk_a3.mc" were updated because this firmware is the only loadable firmware where the QAM demodulator command takes 4 parameters. Some firmwares in the ROM might also use it. The drxk instances in the em28xx-dvb driver were also updated to silence the warnings. If no qam_demod_parameter_count is given in the drxk_config struct, then the correct number of parameters will be auto-detected.

I still have an analog Askey Magic TView card (CHP051, PCI 144f:3002) which I use for radio only. This worked fine with kernel 2.6.37 (openSUSE 11.4), but no longer works with kernel 3.1.10 (openSUSE 12.1). The reason apparently is that ".has_radio = 1" is missing in bttv-cards.c for BTTV_BOARD_MAGICTVIEW061; when I add this line and recompile the kernel, radio is working again. The line is still missing in the latest git tree, for which I have generated the attached patch. I can't test what will happen for CHP05x/CHP06x devices without radio; however, it seems that other cards also have the problem that there are some boards with radio and some without, so I hope that this can be sorted out.
