camera_disable_out_clock()stops the clock for LEDC channelg_ledc_channel. But if the camera was never enabled, it will stop channel 0, which might be used by other things. For instance, on CircuitPython display boards, that channel is usually used for PWM brightness control.This tentative code prevents the clock stop if it was never started.
@jepler We can discuss other ways to do this, maybe inside CircuitPython.
