Subject: [PATCH 1/2] tlan: 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 <[email protected]>

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_TLAN=m

Patch is against 3.0.19-rc7 (localversion = -next-20150203)

Applied.
