From 6d8e9dd050ea78862b6c5e2c873ad6407f9b2428 Mon Sep 17 00:00:00 2001 From: Bryan O'Sullivan Date: Sat, 1 Jul 2006 04:36:14 -0700 Subject: [PATCH] IB/ipath: read/write correct sizes through diag interface We must increment uaddr by size we are reading or writing, since it's passed as a char *, not a pointer to the appropriate size.
