Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6: (841 commits) Staging: brcm80211: fix usage of roundup in structures Staging: bcm: fix up network device reference counting Staging: keucr: fix up US_ macro change staging: brcm80211: brcmfmac: Removed codeversion from firmware filenames. staging: brcm80211: Remove unnecessary header files. staging: brcm80211: Remove unnecessary includes from bcmutils.c staging: brcm80211: Removed unnecessary pktsetprio() function. Staging: brcm80211: remove typedefs.h Staging: brcm80211: remove uintptr typedef usage Staging: hv: remove struct vmbus_channel_interface Staging: hv: remove Open from struct vmbus_channel_interface Staging: hv: storvsc: call vmbus_open directly Staging: hv: netvsc: call vmbus_open directly Staging: hv: channel: export vmbus_open to modules Staging: hv: remove Close from struct vmbus_channel_interface Staging: hv: netvsc: call vmbus_close directly Staging: hv: storvsc: call vmbus_close directly Staging: hv: channel: export vmbus_close to modules Staging: hv: remove SendPacket from struct vmbus_channel_interface Staging: hv: storvsc: call vmbus_sendpacket directly ... Fix up conflicts in drivers/staging/cx25821/cx25821-audio-upstream.c drivers/staging/cx25821/cx25821-audio.h due to warring whitespace cleanups (neither of which were all that great)
