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:

Thanks for your help.
