From: Johan Hedberg Date: Sun, 23 Feb 2014 17:42:24 +0000 (+0200) Subject: Bluetooth: Use hci_update_random_address() for initiating LE scan X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d9483943601ba7095af42a159faacf7746a74bc9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Bluetooth: Use hci_update_random_address() for initiating LE scan When we start LE scanning we need to update the local random address if necessary. This patch updates the code to use hci_update_random_address() for setting the own_address_type scan parameter and updating the local random address if necessary.
