Comment 1 Davy Defaud 2015-06-24 23:03:06 CEST 
I've got a similar DVB-T board working with mga5 kernel and firmwares (kernel-desktop-3.19.8-3.mga5-1-1.mga5 and kernel-firmware-20150309-1.mga5)
Is this bug still valid or can it be closed?

over 9 moths later, still no reply, so assuming this did indeed get fixed.

Please reopen (and update the Source RPM field) if it didn't
