This is only an API consolidation and should make things more readable it replaces var * HZ / 1000 by msecs_to_jiffies(var).
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> ---
Patch was only compile tested with x86_64_defconfig + CONFIG_USB_LEGOTOWER=m
Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
