In the Linux kernel, the following vulnerability has been resolved:
platform/x86: ISST: Restore SST-PP control to all domains
The SST-PP control offset is only restored to power domain 0 after
resume. During suspend, control values are read and stored for all
power domains.
Use pd_info->sst_base instead of power_domain_info->sst_base, which
only points to power domain 0 base address.
