Subject: [patch 6/7] [PATCH] s390: Fix wrong size in memcmp (netiucv)
Date: Tue, 01 Feb 2011 09:16:53 +0100	[thread overview]
Message-ID: <20110201081724.039221197@de.ibm.com> (raw)
In-Reply-To: 20110201081647.173934635@de.ibm.com

[-- Attachment #1: 609-netiucv-memcmp-size.diff --]
[-- Type: text/plain, Size: 849 bytes --]

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

This error was reported by cppcheck:
drivers/s390/net/netiucv.c:568: error: Using sizeof for array given
as function argument returns the size of pointer.

sizeof(ipuser) did not result in 16 (as many programmers would have
expected) but sizeof(u8 *), so it is 4 or 8, too small here.
