Summary
PCI: keystone: Fix NULL pointer dereference in case of DT error in ks_pcie_setup_rc_app_regs()
Details

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

PCI: keystone: Fix NULL pointer dereference in case of DT error in kspciesetuprcapp_regs()

If IORESOURCEMEM is not provided in Device Tree due to any error, resourcelistfirsttype() will return NULL and pciparserequestofpci_ranges() will just emit a warning.

This will cause a NULL pointer dereference. Fix this bug by adding NULL return check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
