From cf745a39dcb10ef80c4a2ff38448f57b69d4c4eb Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Mon, 25 Oct 2010 18:44:11 +0200 Subject: [PATCH] MIPS: Alchemy: fix build with SERIAL_8250=n In commit 7d172bfe ("Alchemy: Add UART PM methods") I introduced platform PM methods which call a function of the 8250 driver; this patch works around link failures when the kernel is built without 8250 support.
