Subject: [PATCH v11 2/3] Bluetooth: Extract generic start and stop discovery
Date: Wed, 26 Nov 2014 14:51:24 -0800 [thread overview]
Message-ID: <1417042285-4779-2-git-send-email-jpawlowski@google.com> (raw)
In-Reply-To: <1417042285-4779-1-git-send-email-jpawlowski@google.com>
This commit extract generic_start_discovery and generic_stop_discovery
in preparation for start and stop service discovery. The reason behind
that is that both functions will share big part of code, and it would
be much easier to maintain just one generic method.
