From 125c97d8a59888c5678734c2b70cbd08c847bd99 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Tue, 13 Jan 2009 22:51:07 +0100 Subject: fix early_serial_setup() regression Commit b430428a188e8a434325e251d0704af4b88b4711 ("8250: Don't clobber spinlocks.") introduced a regression on the parisc architecture, which broke the handover to the serial port at boottime. early_serial_setup() was changed to only copy a subset of the uart_port fields, and sadly the "type" and "line" fields were forgotten and thus the serial port was not initialized and could not be used for a handover. This patch fixes this by copying the missing fields. As this change to early_serial_setup() doesn't need an initialized spinlock in the uart_port struct any longer, we can drop the spinlock initialization in the superio driver.
