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.

On a few places, := were using instead of +=, causing drivers to
not compile.
While here, standardize the usage of += on all cases where multiple
lines are needed, and for obj-y/obj-m targets, and := when just one
line is needed, on <module>-obj rules.

Move the tuners one level up, as the "common" directory will be used
by drivers that are shared between more than one driver.
