Subject: [PATCH 1/2] Bluetooth: Remove unneeded val variable when setting SSP
Date: Thu, 10 Oct 2013 03:08:10 -0700	[thread overview]
Message-ID: <1381399691-42391-1-git-send-email-marcel@holtmann.org> (raw)

The variable val in the set_ssp() function of the management interface
is not needed. Just use cp->val directly since its input values have
already been validated.
