Subject: [PATCH v2 1/2] powerpc/ptdump: Refactor update of st->last_pa
Date: Mon, 29 Jun 2020 11:17:18 +0000 (UTC)	[thread overview]
Message-ID: <610d6b1a60ad0bedef865a90153c1110cfaa507e.1593429426.git.christophe.leroy@csgroup.eu> (raw)

st->last_pa is always updated in note_page() so it can
be done outside the if/elseif/else block.
