[POWERPC] Add null pointer check to of_find_property · 64e4566f

Timur Tabi authored 16 years ago


Update function of_find_property() to return NULL if the device_node
passed to it is also NULL.  Otherwise, passing NULL will cause a null
pointer dereference.

Without this, the legacy_serial driver will crash if there's no
'chosen' node in the device tree.
