X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=642be6c768bd686577ffe6ebcc5e6132a932537b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: Check HCI_PERIODIC_INQ in start_discovery

This patch adds a HCI_PERIODIC_INQ check to start_discovery.
If periodic inquiry is enabled, we fail MGMT Start Discovery
command with MGMT_STATUS_BUSY code.
