Subject: [patch 6/6] [PATCH] s390: Fix possibly wrong size in strncmp (smsgiucv)
Date: Wed, 02 Feb 2011 17:04:36 +0100	[thread overview]
Message-ID: <20110202160530.841230797@de.ibm.com> (raw)
In-Reply-To: 20110202160430.554090958@de.ibm.com

[-- Attachment #1: 610-smsgiucv-strncmp-size.diff --]
[-- Type: text/plain, Size: 951 bytes --]

From: Stefan Weil <weil@mail.berlios.de>

This error was reported by cppcheck:
drivers/s390/net/smsgiucv.c:63: error: Using sizeof for array given as
function argument returns the size of pointer.

Although there is no runtime problem as long as sizeof(u8 *) == 8,
this misleading code should get fixed.
