From 698d070746770aaaec78ab4ffa3ab1f1d5c6abe8 Mon Sep 17 00:00:00 2001 From: Greg Smith Date: Mon, 15 May 2006 09:44:02 -0700 Subject: [PATCH] s390: lcs incorrect test While debugging why our LCS emulator is having some problems I noticed the following weirdness in drivers/s390/net/lcs.c routine lcs_irq. The `if' statement is always true since SCHN_STAT_PCI is defined as 0x80.
