X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4b836f393bd8ed111857a6ee1865e44627266ec6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Bluetooth: Read current IAC LAP on controller setup

Read the current IAC LAP values when initializing the controller. The
values are not used, but it is good to have them in the trace files
for debugging purposes.
