DescriptionIn 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.
