Subject: [PATCH 1/6] Driver core: Fix potential memory leak
Date: Thu, 22 Jul 2010 15:09:01 -0700	[thread overview]
Message-ID: <1279836546-26913-2-git-send-email-ppannuto@codeaurora.org> (raw)
In-Reply-To: <1279836546-26913-1-git-send-email-ppannuto@codeaurora.org>

In both of the 'goto out' cases, priv has already
been allocated and assigned to bus->p. We reset
bus->p to NULL, but neglect to free bus->p
