Subject: [PATCH] timedated: fix enable/disable reversal
1ff636
1ff636
The state was flipped later,
1ff636
but the enable/disable routine made use of the state to decide
1ff636
what to do.
1ff636
1ff636
context_enable_ntp() and context_start_ntp() now get the desired
1ff636
state directly, so the Context parameter can be removed.
