Subject: [PATCH 09/14] powerpc/eeh: Cleanup logic in eeh_rmv_from_parent_pe()
Date: Wed, 12 Sep 2018 11:23:28 +1000	[thread overview]
Message-ID: <7a9a1f802c8f14a90db27e03494e1d7922ef3df9.1536715396.git.sbobroff@linux.ibm.com> (raw)
In-Reply-To: <cover.1536715396.git.sbobroff@linux.ibm.com>

Move the call to eeh_dev_to_pe() up, so that later it's clear that
"pe" isn't NULL.
