Log Message

Bluetooth: fix stuttering audio

commit 2772d76990d8424ef3c629dba164fc7111b37db3 caused
a regression in A2DP for Broadcom Bluetooth chipsets
by not sending the HCI_BRCM_SET_ACL_PRIORITY command.

Change this logic so the ACL priority adjustment occurs
unconditionally for non-Broadcom chipsets only.

Reproduction steps: Entering Bluetooth settings which
triggers inquiry and makes the device discoverable while
simultaneously using 2.4GHz WiFi.
