Subject: [media] dvb-usb: split out common parts of dibusb
Author: Arnd Bergmann <a...@arndb.de>
Date: Tue Jul 19 12:14:34 2016 -0300
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.
