Subject: [PATCH] [5.8 regression] net: ks8851: fix link error
Date: Mon, 25 Jan 2021 13:19:20 +0100 [thread overview]
Message-ID: <20210125121937.3900988-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
An object file cannot be built for both loadable module and built-in
use at the same time:
arm-linux-gnueabi-ld: drivers/net/ethernet/micrel/ks8851_common.o: in function `ks8851_probe_common':
ks8851_common.c:(.text+0xf80): undefined reference to `__this_module'
Change the ks8851_common code to be a standalone module instead,
and use Makefile logic to ensure this is built-in if at least one
of its two users is.
Fixes: 797047f875b5 ("net: ks8851: Implement Parallel bus operations")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Marek sent two other patches to address the problem:
https://lore.kernel.org/netdev/20210116164828.40545-1-marex@denx.de/
https://lore.kernel.org/netdev/20210115134239.126152-1-marex@denx.de/
My version is what I applied locally to my randconfig tree, and
I think this is the cleanest solution.
