From 51e6aace3963d461deec54508840690ca6d492f3 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 9 Nov 2005 18:30:51 +0000 Subject: Moves 32 bit ioctl compat handler to V4L sybsystem From: Arnd Bergmann This moves the 32 bit ioctl compatibility handlers for Video4Linux into a new file and adds explicit calls to them to each v4l device driver. Unfortunately, there does not seem to be any code handling the v4l2 ioctls, so quite often the code goes through two separate conversions, first from 32 bit v4l to 64 bit v4l, and from there to 64 bit v4l2. My patch does not change that, so there is still much room for improvement. Also, some drivers have additional ioctl numbers, for which the conversion should be handled internally to that driver.
