Newer firmware versions put different data in the memory which is read by the driver upon firmware crash. Just change the variable names in the code and the name of the data in the log that we print withouth any functional change. On older firmware, there will be a mismatch between the names that are printed and the content itself, but that's harmless. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
