Description Jan ONDREJ 2013-01-15 09:25:58 UTC 
Created attachment 678680 [details]
Diff compiled modules from build logs.

Description of problem:
After update to kernel 3.7.2, my DVB-T USB stick is not functional due to missing driver. There is no af9013.ko module in kernel or kernel-modules-extra packages.

Version-Release number of selected component (if applicable):
kernel-3.7.2-201.fc18.x86_64
kernel-modules-extra-3.7.2-201.fc18.x86_64

How reproducible:
always

Steps to Reproduce:
1. yum update
2. modinfo af9013
  
Actual results:
ERROR: Module af9013 not found.

Additional info:
After downgrade to 3.6.10 kernel my problem was solved.
According to koji logs, this driver was not configured to build (missing CONFIG_DVB_AF9013=m).

Comment 1 Josh Boyer 2013-01-15 14:23:36 UTC 
Mauro, I'm fairly sure this is a result of CONFIG_MEDIA_SUBDRV_AUTOSELECT defaulting to =y in the 3.7 kernels.  With that set, we can't individually enable this module.  Should it be added to the AUTOSELECT list?

Yes. This device is a frontend:

$ git grep CONFIG_DVB_AF9013 drivers/media/
drivers/media/dvb-frontends/Makefile:obj-$(CONFIG_DVB_AF9013) += af9013.o
drivers/media/dvb-frontends/af9013.h:#if defined(CONFIG_DVB_AF9013) || \
drivers/media/dvb-frontends/af9013.h:     (defined(CONFIG_DVB_AF9013_MODULE) && defined(MODULE))
drivers/media/dvb-frontends/af9013.h:#endif /* CONFIG_DVB_AF9013 */

$ git grep af9013.h drivers/media/
drivers/media/dvb-frontends/af9013_priv.h:#include "af9013.h"
drivers/media/usb/dvb-usb-v2/af9015.h:#include "af9013.h"

The only driver that uses it is af9015. Its Kconfig should be autoselecting it.
At least on the current upstream, this seems to be correct:

config DVB_USB_AF9015
        tristate "Afatech AF9015 DVB-T USB2.0 support"
        depends on DVB_USB_V2
        select DVB_AF9013
Comment 3 Josh Boyer 2013-01-15 15:59:36 UTC 
OK.  We don't have DVB_USB_V2 set, so that doesn't show up.  That would be the issue I guess.
Comment 4 Josh Boyer 2013-01-15 16:01:32 UTC 
Fixed in Fedora git.
