This patch fixes the below issues w.r.t jack implementation a) The current jack implementation in driver is implemented in intelmid.c. It has moved to vendor files for better managebility b) Cleaned up jack reporting per upstream comments c) Implemented jack for msic, added code to read adc and deduce jack type based on mic bias d) Support detection of american headset Signed-off-by: Dharageswari R <dharageswari.r@intel.com> Signed-off-by: Ramesh Babu K V <ramesh.babu@intel.com> [Corrections] Signed-off-by: Lu Guanqun <guanqun.lu@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
