From: Johan Hedberg Date: Tue, 21 Feb 2012 15:25:22 +0000 (+0200) Subject: Bluetooth: mgmt: Fix pairable setting upon initialization X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0cbf4ed6e6f43ac399afefdd14a1ee86db8de7d0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Bluetooth: mgmt: Fix pairable setting upon initialization When mgmt is not in use the HCI_PAIRABLE flag will get implicitly set so that pairing still works with old user space versions. However, as soon as mgmt comes into play we should clear this flag so that it can be properly set through the set_pairable command by user space.
