From: Andre Guedes Date: Thu, 1 Mar 2012 21:19:57 +0000 (-0300) Subject: Bluetooth: Don't force DISCOVERY_STOPPED state in inquiry_cache_flush X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=74fe619ef96466d562a1a13e7cbab783624ec2f3;p=openwrt%2Fstaging%2Fblogic.git Bluetooth: Don't force DISCOVERY_STOPPED state in inquiry_cache_flush We are not supposed to force DISCOVERY_STOPPED in inquiry_cache_flush because we may break the discovery state machine. For instance, during interleaved discovery, when we are about to start inquiry, the state machine forcibly goes to DISCOVERY_STOPPED while it should stay in DISCOVERY_FINDING state. This problem results in unexpected behaviors such as sending two mgmt_discovering events to userspace (when only one event is expected) and Stop Discovery failures.
