X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b3af7334bd3c403647606adfb04f6e6bcf1597e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: Split error handling for L2CAP listen sockets

Split the checks for sk->sk_state and sk->sk_type for L2CAP listen
sockets. This makes the code more readable.
