X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c893779e9fbe78575cbd04596f1fcafdb48e8f3f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[Bluetooth] Handle device registration failures

In the case the device registration for a new Bluetooth low-level
connection fails there is no need to unregister it when the temporary
data structure has been removed.
