From: Mauro Carvalho Chehab Date: Mon, 26 Dec 2011 18:31:22 +0000 (-0300) Subject: [media] af9005-fe: convert set_fontend to use DVBv5 parameters X-Git-Tag: firefly_0821_release~3680^2~2904^2~340 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f9e54512fd16379812bcff86d95d0a7d78028b20;p=firefly-linux-kernel-4.4.55.git [media] af9005-fe: convert set_fontend to use DVBv5 parameters Instead of using dvb_frontend_parameters struct, that were designed for a subset of the supported standards, use the DVBv5 cache information. Also, fill the supported delivery systems at dvb_frontend_ops struct.
