From 9468542bf29ba6cdc9d052a7b9aa384279b0f845 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 5 Aug 2012 14:16:29 -0300 Subject: [media] dvb core: remove support for post FE legacy ioctl intercept This DVB_FE_IOCTL_POST isn't used, so remove it. Also, intercepting ioctl's like that only works with legacy ioctl's, due to the way it was implemented. so this design is broken. Document it.
