Subject: [PATCH 2/2] tlan: msecs_to_jiffies convrsion

This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).

As there is a discrepancy between the code and the comments this is in
a separate patch.

Signed-off-by: Nicholas Mc Guire <>

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 basically is a minor API cleanup only
but the comment and the code do not match ! Comments states "do the
longer, just in case" which would be 500 ms - the code though sets it
to HZ/20 == 50ms. This needs a review by someone that knows the driver
details to decide if it should be 50 or 500ms here.

Patch was only compile tested for x86_64_defconfig + CONFIG_TLAN=m

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