Subject: [PATCH] powerpc: non-GPL export for eeh_dev_check_failure

EEH kernel services are inconsistently exported by the 
kernel. eeh_check_failure is exported for any use, but 
eeh_dev_check_failure is exported only for GPL use. 
While eeh_check_failure is implemented for a specific 
purpose to be used by services such as readl, it is 
not suited for a purpose where caller needs eeh status. 
This functionality is provided by eeh_dev_check_failure.

This patch relaxes the export for eeh_dev_check_failure
to make it consistent with eeh_check_failure() and 
usable by non-GPL modules.
