## Overview

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

ACPI: RISC-V: Check acpi_get_handle() status in riscv_acpi_add_prt_dep()

In riscv_acpi_add_prt_dep(), the acpi_get_handle() call can fail which
would leave link_handle uninitialized.

Fix it by checking the acpi_get_handle() return status and skip the entry
if it fails.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
