[PATCH master] i2c: don't return error pointers from of_find_i2c_adapter_by_node

[Ahmad Fatoum]

All callers of of_find_i2c_adapter_by_node expect errors to be indicated
by NULL and don't check non-NULL pointers with IS_ERR().

Therefore map of_device_ensure_probed() errors to NULL as well to avoid
dereferencing error pointers.
