CVE-2023-53787

In the Linux kernel, the following vulnerability has been resolved:

regulator: da9063: fix null pointer deref with partial DT config

When some of the da9063 regulators do not have corresponding DT nodes a null pointer dereference occurs on boot because such regulators have no init_data causing the pointers calculated in da9063_check_xvp_constraints() to be invalid.

Do not dereference them in this case.
