[REGRESSION] After upgraded to ubuntu 12.04.02, snd-bt87x driver lost the functionality of load_all parameter.

[Triniton Adam]

After migrate from ubuntu 12.04.1 (where my tvtuner card is detected by snd-bt87x module, see alsa-info output at:
http://www.alsa-project.org/db/?f=c51c79be707968f29e4a54c6b4d93a030a18d2d2), to ubuntu 12.04.2, module not more recognized my bt87x card.

Conceptronic CTVFMi v2 [036e:109e]

What has changed in 12.04.2 because snd-bt87x module not recognized my bt87x card ?

In ubuntu 12.04.1 module work:

$ cat /proc/asound/cards
 0 [ICH5 ]: ICH4 - Intel ICH5
                  Intel ICH5 with ALC850 at irq 17
 1 [bttv ]: Bt87x - Brooktree Bt878
                  Brooktree Bt878 at 0xf7eff000, irq 20

you have to post the system log and output of alsa-info.sh for 12.04.2

For 12.04.2 output of alsa-info.sh is located at http://www.alsa-project.org/db/?f=62c56d54bcae54bc6a4e751e612790194192f068

warning when build from snapshot and four sound card modules are warned

Section mismatch in reference from the function snd_bt87x_detect_card() to the variable .devinit.rodata:snd_bt87x_ids
The function snd_bt87x_detect_card() references
the variable __devinitconst snd_bt87x_ids.
This is often because snd_bt87x_detect_card lacks a __devinitconst
annotation or the annotation of snd_bt87x_ids is wrong.
