I forgot about it at the time but f02b4b72d12c (clockevents/tcb_clksrc: Prevent disabling an already disabled clock) was sufficient to remove the warning. Your patch is still Ok but maybe it can get rid of the "if (!clockevent_state_detached(d))" in tc_shutdown_clk_off() I'll test and take care of that. > So I will apply this to get rid of the warning.
