[PATCH] Altix serial: fix

From: roel kluin
Date: Sun Jul 20 2008 - 05:14:47 EST


Patch was not tested on hardware
---
In function sn_sal_switch_to_asynch(): drivers/serial/sn_console.c:713:

HZ * SN_SAL_UART_FIFO_DEPTH / SN_SAL_UART_FIFO_SPEED_CPS;

After preprocessing (see defines in patch) this becomes HZ * 16 / 9600 / 10
(associativity from left to right), not equivalent to HZ * 16 / 960.
