Subject: [PATCH 1/3] wireless: orinoco: orinoco_plx use msecs_to_jiffies for conversion

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@...dl.org>
---

Converting milliseconds to jiffies by "val * HZ / 1000" is technically
ok but msecs_to_jiffies(val) is the cleaner solution and handles all
corner cases correctly. This is a minor API cleanup only.

Patch was compile-tested only for x86_64_defconfig + CONFIG_HERMES=m
CONFIG_PLX_HERMES=m

Patch is against 3.19.0-rc7 (localversion-next is -next-20150203)
