From 3a3a7f3b7fbd3c2f2ca2f2bf76363a1abbd5ba94 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 29 Sep 2015 10:24:02 +0200 Subject: [PATCH] net: mac8390: Allow modular build The modular driver supports only one card, just like the built-in driver. Note that this limitation is a problem which affects all Nubus card drivers, because they have to do all their own bus matching, because Nubus still lacks the necessary driver model support.
