2008-09-16V4L/DVB:usbvideo:don't use part of buffer for USB transfer #4Mauro Carvalho Chehab
From: Ming Lei <tom.leiming@gmail.com> The status[] is part of uvc_device structure. We can't make sure the address of status is at a cache-line boundary in all archs,so status[] might share a cache-line with some fields in uvc_structure. This can lead to some cache coherence issues(http://lwn.net/Articles/2265/). Use dynamically allocated buffer instead.

2008-07-04uvcvideo: Don't free URB buffers on suspend.Mauro Carvalho Chehab
From: Laurent Pinchart <laurent.pinchart@skynet.be> All submitted URBs must be killed at suspend time, but URB buffers don't have to be freed. Avoiding a free on suspend/reallocate on resume lowers the presure on system memory.

USB Video Class driver This driver supports video input devices compliant with the USB Video Class specification. This means lots of currently manufactured webcams, and probably most of the future ones.
