Re: [PATCH] Add null pointer check to of_find_property

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

Paul, please pick this up for 2.6.26.  The legacy_serial driver will crash
without it if there's no 'chosen' node in the device tree.  I'm sure there are
other drivers that would crash similarly if given a device tree with missing nodes.
