From b655c2c4782ed3e2e71d2608154e295a3e860311 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Mon, 24 Sep 2012 17:20:52 +0100 Subject: staging: comedi: s626: don't dereference insn->data `s626_enc_insn_config()` is incorrectly dereferencing `insn->data` which is a pointer to user memory. It should be dereferencing the separate `data` parameter that points to a copy of the data in kernel memory.
