2020-07-26drivers/usb: Avoid NULL pointer dereferenceJohn Zhao
Coverity detects dereferencing pointers that might be "NULL" when calling acpigen_write_scope and acpigen_write_device. Add sanity check for both of scope and name to prevent NULL pointer dereference. Found-by: Coverity CID 1430454 TEST=Built and boot up to kernel on Volteer.

2020-07-12drivers/usb/pci_xhci: Don't return ACPI names for missing portsRaul E Rangel
We only want to return an ACPI name for a USB port if the controller physically has the port. This has the desired side effect of making the usb_acpi driver skip generating an ACPI node for a device which has no port. This prevents writing an invalid SSDT table which the OS then complains about. BUG=b:154756391, b:158096224 TEST=Boot picasso trembyle and verify HS05, HS06 and SS05 are no longer generated. Also checked the logs and saw the devices being ignored. \_SB.PCI0.LPCB.EC0.CREC.TUN0: Cros EC I2C Tunnel at GENERIC: 0.0 \_SB.PCI0.LPCB.EC0.CREC.MSTH: Cros EC I2C Tunnel at GENERIC: 1.0 \_SB.PCI0.LPCB.EC0.CREC.ECA0: Cros EC audio codec at GENERIC: 0.0 \_SB.PCI0.PBRA.XHC0.RHUB.HS01: Left Type-C Port at USB2 port 0 \_SB.PCI0.PBRA.XHC0.RHUB.HS02: Left Type-A Port at USB2 port 1 \_SB.PCI0.PBRA.XHC0.RHUB.HS03: Right Type-A Port at USB2 port 2 \_SB.PCI0.PBRA.XHC0.RHUB.HS04: Right Type-C Port at USB2 port 3 xhci_acpi_name: USB2 port 4 does not exist on xHC PCI: 03:00.3 xhci_acpi_name: USB2 port 5 does not exist on xHC PCI: 03:00.3 \_SB.PCI0.PBRA.XHC0.RHUB.SS01: Left Type-C Port at USB3 port 0 \_SB.PCI0.PBRA.XHC0.RHUB.SS02: Left Type-A Port at USB3 port 1 \_SB.PCI0.PBRA.XHC0.RHUB.SS03: Right Type-A Port at USB3 port 2 \_SB.PCI0.PBRA.XHC0.RHUB.SS04: Right Type-C Port at USB3 port 3 xhci_acpi_name: USB3 port 4 does not exist on xHC PCI: 03:00.3 Signed-off-by: Raul E Rangel <rrangel@chromium.org> Change-Id: Ia645380bea74f39fd94e2f9cbca3fcd4d18a878e Reviewed-on: https://review.coreboot.org/c/coreboot/+/43354 Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Rob Barnes <robbarnes@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
