First of all, as is evident here, I am the original reporter, not Laura Abbott <labbott@xxxxxxxxxx>. -All- your comments including the final patch on this issue, are just plain wrong.[1] This patch only hides the actual problem with this particular device - the dual tuner combination driven by dvb_usb_af9015 & mxl5007t, broken by design since day one. Read the entire https://bugzilla.redhat.com/show_bug.cgi?id=1252167 and stop this nonsense.
