Subject: [PATCH 3/4] powerpc: pseries: only store the device node basename in full_name
Date: Tue, 25 Jul 2017 16:44:26 -0500 [thread overview]
Message-ID: <20170725214427.25768-4-robh@kernel.org> (raw)
In-Reply-To: <20170725214427.25768-1-robh@kernel.org>
With dependencies on full_name containing the entire device node path
removed, stop storing the full_name in nodes created by
dlpar_configure_connector() and pSeries_reconfig_add_node().
