From 6e87abd0b8cbb23ed9ffe5cc9f790fb5cac45eae Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 16 Nov 2005 00:52:57 -0800 Subject: [DVB]: Add compat ioctl handling. Based upon a patch by Guido Guenther . Some of these ioctls had embedded time_t objects or pointers, so needed translation. Signed-off-by: David S.
