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>

Converting milliseconds to jiffies by val * HZ / 1000 is technically
not wrong but msecs_to_jiffies(val) is the cleaner solution and handles
all corner cases correctly. This is a minor API cleanup only.
Patch was only compile tested for x86_64_defconfig + CONFIG_SOUND=y,
CONFIG_SND_USB_POD=m (implies CONFIG_SND_USB_LINE6=y)
Patch is against 3.0.19-rc6 (localversion = -next-20150202)
