From 48c7aba91f372251867d15efc9cf694ceee2de02 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 19 Feb 2012 14:06:48 +0200 Subject: [PATCH] Bluetooth: Fix hci_connect error return values The hci_connect function should either return a valid hci_conn pointer or a ERR_PTR() but never NULL. This patch fixes the two places where hci_conn_add failures would have caused a NULL return. The only reason for failure with hci_conn_add is memory allocation so ENOMEM seems to be a good choice here.
