Subject: Bluetooth: Simplify address parameters of user_pairing_resp()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1707c60e5d0d4c82c0601d92f10e24e04d2cc599;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: Simplify address parameters of user_pairing_resp()

Instead of passing the bdaddr and bdaddr_type as separate parameters to
user_pairing_resp it's simpler to just pass the original mgmt_addr_info
struct which contains both values.
