## Overview

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

ACPI: RISC-V: Fix riscv_acpi_add_prt_dep() loop handling

The loop in riscv_acpi_add_prt_dep() includes error conditions that are
handled in a dubious - if not outright wrong - way, by continuining the
loop (which skips and misses the entry pointer update to point to the next
entry).

Rewrite the loop as a for loop (that handles the continuation correctly)
and wrap the condition and update statements using helper functions to make
it cleaner.

## Remediation

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