From: Mauro Carvalho Chehab Date: Sat, 4 Aug 2012 19:05:34 +0000 (-0300) Subject: [media] az6007: convert it to use dvb-usb-v2 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=255d52f25485e8fe244d15266b76428ba545f022;p=openwrt%2Fstaging%2Fblogic.git [media] az6007: convert it to use dvb-usb-v2 Change it to use dvb-usb-v2. The driver should be working as before. The only functional changes should be at the driver debug logs. This driver needs the cypress firmware load, so, auto-selects it.
