From c91fcc9b460397a85a6bd1d8f441d8da5abac415 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 30 Dec 2008 10:58:20 +0100 Subject: v4l2: introduce v4l2_file_operations. From: Hans Verkuil Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.
