Subject: [PATCH] ioatdma: make debug output more readable
Date: Mon, 04 Mar 2013 10:59:54 -0700 [thread overview]
Message-ID: <20130304175954.9792.19327.stgit@djiang5-linux2.ch.intel.com> (raw)
Making OP field a hex instead of integer to make it more readable. Also add
the dump out of the NEXT field.
