What about these other users of cap_raised?

drivers/block/drbd/drbd_nl.c: if (!cap_raised(nsp->eff_cap, CAP_SYS_ADMIN)) {
drivers/md/dm-log-userspace-transfer.c: if (!cap_raised(nsp->eff_cap, CAP_SYS_ADMIN))
drivers/staging/pohmelfs/config.c: if (!cap_raised(nsp->eff_cap, CAP_SYS_ADMIN))
drivers/video/uvesafb.c: if (!cap_raised(nsp->eff_cap, CAP_SYS_ADMIN))

Also, should this have a reported-by for Eric ?
