Gustavo A. R. Silva ce02d82c4e mfd: sm501: Fix potential NULL pointer dereference
commit ae7b8eda27 upstream.

There is a potential NULL pointer dereference in case devm_kzalloc()
fails and returns NULL.

Fix this by adding a NULL check on *lookup*

This bug was detected with the help of Coccinelle.
