Description
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.
