From 5b1efd0176c2e32a5f6766175e518ccfc45239a6 Mon Sep 17 00:00:00 2001 From: Santeri Salko Date: Thu, 13 Jan 2011 15:21:06 +0200 Subject: [PATCH] str9xpec: Find flash controller from the chain. Find the flash controller by position since it is before the core, not after it. This fixes the problem that str9xpec enable_turbo (or any other str9xpec command) did not work.
