Subject: Re: [PATCH] Bluetooth: hci_qca: Make structure qca_proto constant

Hi Nishka,

> Static structure qca_proto, of type hci_uart_proto, is used four times:
> as the last argument in function hci_uart_register_device(), and as the
> only argument to functions hci_uart_register_proto() and
> hci_uart_unregister_proto(). In all three of these functions, the
> parameter corresponding to qca_proto is declared as constant. Therefore,
> make qca_proto itself constant as well in order to protect it from
> unintended modification.
