漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:PCI: endpoint: epf-mhi: Avoid NULL dereference if DT lacks mmio If platform_get_resource_byname() fails and returns NULL because DT lacksan mmio property for the MHI endpoint, dereferencing res->start willcause a NULL pointer access. Add a check to prevent it.[kwilczynski: error message update per the review feedback][bhelgaas: commit log]
