Subject: [PATCH v2 7/9] powerpc/eeh: Remove always-true tests in eeh_reset_device()
Date: Mon, 19 Mar 2018 13:49:04 +1100	[thread overview]
Message-ID: <5a636a21f3352efa7a41bf4032f3a57973c4c18b.1521427331.git.sam.bobroff@au1.ibm.com> (raw)
In-Reply-To: <cover.1521427331.git.sam.bobroff@au1.ibm.com>

eeh_reset_device() tests the value of 'bus' more than once but the
only caller, eeh_handle_normal_device() does this test itself and will
never pass NULL.

So, remove the dead tests.

This should not change behaviour.
