cfs_time_sub subtracts finds the difference.
Discard these and use '+' and '-' directly.

This change highlighted a type error.  The structure field
cr_queued_time was used to store jiffies, but was declared
as time_t (meant for seconds).  So the time is changed to

Move the initialization of these two fields together with the

parameters, prior to the heap allocate() call, for consistency.

1/ the return value of ldlm_resource_putref() is never
  used, so change it to return 'void'.
2/ Move all of the code to run on the last putref to
   __ldlm_resource_putref_final().  This means a lock
   is taken in one function and dropped in another, but
   that isn't too uncommon, and will disappear in a future
   patch.
   Now that the code it together, it becomes apparent that
   we are dropping a ref on the namespace *before* the last

This commit refactors ks_wlan_set_encode function to improve

as well as removes not needed conditions paths which was

 - (dwrq->length > MAX_KEY_SIZE) check has been moved to the top.
 - extra check about (dwrq->length > 0) inside an if block where
   that was the condition to enter inside it has been removed.
 - (dwrq->flags & IW_ENCODE_NOKEY) check has been turned to avoid
   one level indentation.
 - extra check (index >= 0) && (index < 4) has been removed. In
   the top of the file invalid index values are being checked
   so it has no sense to check that again.
 - remove commented line.

This commit removes the local buffer zeros in ks_wlan_get_encode
function. It also refactors related conditions in order to fill
'extra' output parameter of the function. Originally this zeros
is just memset to zeros and only being used if drw->length is
truncated to zero because of priv->reg.wep_key[index].size is
greater than 16 chars. In those cases the final if statement is
just using zeros but it is using memcpy with a length of zero
bytes which has no sense. Instead of that just handle the good
case copying from the same source the number of bytes of
priv->reg.wep_key[index].size. If it is zero the final 'extra'
parameter won't be copied at all because the number of bytes to
copy will be zero. With this change the code gets simplified.
