Subject[PATCH -next] powerpc/44x/fsp2: add missing of_node_put
Date
Early exits from for_each_compatible_node() should decrement the
node reference counter. Reported by Coccinelle:

./arch/powerpc/platforms/44x/fsp2.c:206:1-25: WARNING: Function
"for_each_compatible_node" should have of_node_put() before return
around line 218.

Fixes: 7813043e1bbc ("powerpc/44x/fsp2: Add irq error handlers")
