From 333ae95d054519f64303f0e149b4b9653cc4635b Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 17 Mar 2015 13:48:47 +0200 Subject: [PATCH] Bluetooth: Add channel parameter to mgmt_pending_find() API To be able to have pending commands for different HCI channels we need to be able to distinguish for which channel a command was sent to. The channel information is already part of the socket data and can be fetched using the recently added hci_sock_get_channel() function. To not require all mgmt.c code to pass an extra channel parameter this patch also adds a helper pending_find() & pending_find_data() functions which act as a wrapper to the new mgmt_pending_find() & mgmt_pending_find_data() APIs.
