From 44b1c5b02d09f608ab17baeed5f5862af30bb32e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 31 May 2009 22:05:55 +0200 Subject: uvcvideo: Add generic control blacklist. From: Laurent Pinchart Another device (5986:0241) has been reported to advertise a UVC control it does not support. Rework the control blacklist to match devices by their VID:PID instead of trying to be clever about which controls might not be supported properly.

From: Laurent Pinchart Setting a new frame format or size will likely change the buffer size required to store a complete video frame. To avoid a buffer overflow, don't allow VIDIOC_S_FMT calls when video buffers are already allocated.
