Linux 2.6.39-rc2

Looks like there is an issue with building a driver in staging

  LD [M]  drivers/staging/hv/hv_netvsc.o
  LD [M]  drivers/staging/hv/hv_utils.o
  CC [M]  drivers/staging/hv/hv_mouse.o

drivers/staging/hv/hv_mouse.c: In function ‘ReleaseInputDevice’:
drivers/staging/hv/hv_mouse.c:293: error: implicit declaration of function ‘udelay’
make[4]: *** [drivers/staging/hv/hv_mouse.o] Error 1 make[3]: *** [drivers/staging/hv] Error 2
make[2]: *** [drivers/staging] Error 2

Seems to be just a missing header in drivers/staging/hv/hv_mouse.c (to be precise linux/delay.h as the file uses udelay()) this patch fixes the issue:
