From d5f2d2be68876f65dd051b978a7b66265fde9ffd Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 16 Feb 2009 02:57:30 +0100 Subject: [PATCH] Bluetooth: Fix poll() misbehavior when using BT_DEFER_SETUP When BT_DEFER_SETUP has been enabled on a Bluetooth socket it keeps signaling POLLIN all the time. This is a wrong behavior. The POLLIN should only be signaled if the client socket is in BT_CONNECT2 state and the parent has been BT_DEFER_SETUP enabled.
