From bec43661b1dc0075b7445223ba775674133b164d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 30 Dec 2008 06:58:20 -0300 Subject: V4L/DVB (10135): v4l2: introduce v4l2_file_operations. 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.

Since both cards use the same driver, it tries to create the analog dev for both devices, which is not possible. This causes a NULL error to show up in video_open and mpeg_open. -Mark Iterations through the cx23885_devlist must check for NULL pointers as some supported devices only have DVB support at the moment.
