From bc20589bf1c63e4e8bee57855568458ba303306b Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 15 Oct 2008 22:04:18 -0700 Subject: [PATCH] applicom.c: fix apparently-broken code in do_ac_read() The code scriblles over a local pointer whereas it appears to be trying to write to the memory at which that pointer points. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=11397 Nobody we know can test this change.
