From d63beb9ef004ff9587b3c466361276254d57d7a7 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 15 Sep 2008 22:24:29 -0300 Subject: [PATCH] V4L/DVB (9031): uvcvideo: Fix incomplete frame drop when switching to a variable size format. When streaming in a fixed size format the driver sets a flag in the uvc_queue structure to drop incomplete incoming frames. The flag wasn't cleared when switching to a variable size format, which resulted in a broken 'MJPEG after YUV'.
