[media] dvb-usb: split out common parts of dibusb
Tha ARM randconfig builds came up with another rare build failure for the dib3000mc driver, when dvb-usb-dibusb-mb is built-in and dib3000mc is a loadable module: ERROR: "dibusb_dib3000mc_frontend_attach" [drivers/media/usb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! ERROR: "dibusb_dib3000mc_tuner_attach" [drivers/media/usb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! Apparently this used to be a valid configuration (build-time, not run-time), but broke as part of a cleanup. I tried reverting the cleanup, but saw that the code was still wrong then. This tries to fix the code properly, by moving the problematic functions into a new file that now is built as a loadable module or built-in, whichever is correct for a particular configuration. It fixes the regression as well as the runtime problem that already existed. The new module dependency chain is now: dvb-usb-{dibusb_mc,a800,dib0700,umt-010,gp8psk} dvb-usb-dibusb-mb | | | | dvb-usb-dibusb-mc-common | ___________| | | | | | | dib3000mc (frontend) | | | dib3000mb (frontend) | | | | | | dvb-usb-dibusb-common I have also checked the two other files that were changed in the original cleanup, and found them to be correct in either version, so I do not touch that part. As this is a rather obscure bug, there is no need for backports.
