Hi, I am facing broken audio issues when using the broadcom bt chip especially when it comes back from suspend. While debugging the issue, What is the purpose of doing a registering a ldisc in the driver using the call tty_register_ldisc call() in Bluetooth drivers which deal with power management. I am referring to the below driver: https://android.googlesource.com/kernel/bcm/+/android-4.4w_r6/drivers/misc/bcm-bt-lpm.c Thanks for your help.
