[PATCH] powerpc: Fix call to ibm,client-architecture-support
The code in prom_init.c calling the firmware ibm,client-architecture-support method on pSeries has a bug where it fails to properly pass the instance handle of the firmware object when trying to call a method. Result ranges from the call doing nothing to the firmware crashing. (Found by Segher, thanks !)
