V4L/DVB:usbvideo:don't use part of buffer for USB transfer #4
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.
