Subject[PATCH] usb: isp1760: use msecs_to_jiffies for time conversion
Date
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_ISP1760=m

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
