ASoC: rt5665: calibration should be done before jack detection
We will set some volatile registers in jack detection function. But those volatile registers will be clear in rt5665_calibrate function because we set cache bypass and reset codec in rt5665_calibrate function. This patch add a flag to make sure that rt5665_calibrate is done before starting jack detection. Signed-off-by: Bard Liao <bardliao@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
