From 9adf6132dca24240fbc26c6e5e095734fa366341 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 5 Aug 2012 14:16:30 -0300 Subject: [PATCH] [media] dvb: get rid of fe_ioctl_override callback This callback were meant to allow overriding a FE callback, before its call, but it is not really needed, as the callback can be intercepted after tuner attachment. Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5 application will produce different effects than a DVBv3 one. So, get rid of it.
