From cca30245bd6a5a713f0dc3278c37d9bd1f726e72 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Thu, 18 Jun 2009 13:42:24 +0800 Subject: [PATCH] intel: Do not access pbo's buffer directly when attaching. pbo might be system buffer based or attached to another region. Call intel_bufferobj_buffer to make sure pbo has a buffer of its own.
