Johan Hovold f61c43be1e regmap: fix NULL deref on lookup 
commit c6df843348 upstream.

Not all regmaps have a name so make sure to check for that to avoid
dereferencing a NULL pointer when dev_get_regmap() is used to lookup a
named regmap.

Fixes: e84861fec3 ("regmap: dev_get_regmap_match(): fix string comparison")
