[PATCH] bus: arm-integrator-lm: Fix an IS_ERR() vs NULL check

The of_find_matching_node() function returns NULL on error, it never returns error pointers. This doesn't really impact runtime very much because if "syscon" is NULL then syscon_node_to_regmap() will return -EINVAL. The only runtime difference is that now it returns -ENODEV. Fixes: ccea5e8a5918
