From ca3fd11ab544a2fb75c6cb9223ed4d0351b7db1b Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Thu, 21 Oct 2021 21:07:01 +0800 Subject: [PATCH] ptp: dp83640: don't define PAGE0 stable inclusion from stable-5.10.68 commit f6f80766558b72d59bd7a25519abc55c71c126c7 bugzilla: 182671 https://gitee.com/openeuler/kernel/issues/I4EWUH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=f6f80766558b72d59bd7a25519abc55c71c126c7 -------------------------------- commit 7366c23ff492ad260776a3ee1aaabba9fc773a8b upstream. Building dp83640.c on arch/parisc/ produces a build warning for PAGE0 being redefined. Since the macro is not used in the dp83640 driver, just make it a comment for documentation purposes.
