Subject: [PATCH] ADE7953: Fix dereferencing of a null pointer (#1086)

* ADE7953: Fix dereferencing of a null pointer

The ade7953 driver dereferences a null pointer, when not all of
its sensors are used. This gives an exception like:

Fatal exception:29 flag:2 (EXCEPTION) epc1:0x4020c241 epc2:0x00000000 epc3:0x00000000 excvaddr:0x00000018 depc:0x00000000

* Fix formatting
