Subject: [PATCH] Bluetooth: hci_bcm: Drive RTS only for BCM43438

commit e601daed271e9eb1b923972a0a1af65f8c7bb77b upstream.
|
||
|
|
|
||
|
|
The commit 3347a80965b3 ("Bluetooth: hci_bcm: Fix RTS handling during
|
||
|
|
startup") is causing at least a regression for AP6256 on Orange Pi 3.
|
||
|
|
So do the RTS line handing during startup only on the necessary platform.
|
||
|
|
|
||
|
|
Fixes: 3347a80965b3 ("Bluetooth: hci_bcm: Fix RTS handling during startup")
