[Arm-dev] Issues with the 4.9.x kernel and pvrusb2 driver

[Pablo Sebastián Greco]

Chris, I think you are on the right track.
Reverting commit 
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/drivers/media/usb/pvrusb2/pvrusb2-eeprom.c?h=v4.9.80&id=374aceef5912f3438a1cc582a2007551f0fbdb15 
on both stable 4.4 and 4.9 should fix the issue because neither of those 
branches received these commits 
(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/drivers/media/common/tveeprom.c?id=7cda4c5bae46ffca3abeadc4c1882d9325ee3102 
, 
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/drivers/media/common/tveeprom.c?id=6037b3ca28f4258d913dbe77248fd77827702ae3) 
so null is an invalid way to call.
I think you should file a bug with this info on bugzilla.kernel.org and 
go from there.
 From the CentOS standpoint, don't know if such a patch could be 
applied, for next update, don't really have the authority there....

HTH.
Pablo.
