Subject: [PATCH -v2 2/8] PCI: release temporary reference in __nv_msi_ht_cap_quirk()
Date: Mon, 09 Jul 2012 15:36:08 -0600	[thread overview]
Message-ID: <20120709213608.8975.90022.stgit@amt.stowe> (raw)
In-Reply-To: <20120709213554.8975.60552.stgit@amt.stowe>

__nv_msi_ht_cap_quirk() acquires a temporary reference via
'pci_get_bus_and_slot()' that is never released.

This patch releases the temporary reference.
