In commit e5c02cf54154 ("i2c: mv64xxx: Add runtime PM support"), error
pointers to optional clocks were replaced by NULL to simplify the resume
callback implementation. However, that commit missed that the IS_ERR
check in mv64xxx_of_config should be replaced with a NULL check. As a
result, the check always passes, even for an invalid device tree.
