From d0fe85e95f56a01a49e4893aa26263e8aee67eef Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 19 Jul 2016 12:14:35 -0300 Subject: [PATCH] [media] dvb-usb: avoid link error with dib3000m{b,c| 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 version adds a dependency for dib3000mb, to ensure that dib3000mb does not force the dibusb_dib3000mc_frontend_attach function to be built-in when dib3000mc is a loadable module. 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.
