[PATCH] [POWERPC] pasemi: ioremap/iounmap balance and failure handling

map_onedev can return NULL, so catch that. Also iounmap if DMA controller can't be found. Signed-off-by: Roel Kluin --- UNTESTED! I am a bit new, so please confirm whether this is correct. especially: * can we iounmap while init_lock is held? * is it ok to add another BUG() here? diff --git
