Subject: af_iucv: handle non-accepted sockets after resuming from suspend
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=56a73de3889383b70ed1fef06aaab0677731b0ea;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

af_iucv: handle non-accepted sockets after resuming from suspend

After resuming from suspend, all af_iucv sockets are disconnected.
Ensure that iucv_accept_dequeue() can handle disconnected sockets
which are not yet accepted.
