PR for series 1091950 applied to workflow__riscv__fixes

Name: [v2] riscv: Check the return value of reloc handlers
URL: https://patchwork.kernel.org/project/linux-riscv/list/?series=1091950
Version: 2

Linux RISC-V bot and others added 2 commits May 2, 2026 08:13
Currently, process_accumulated_relocations() ignores the return values
from both reloc_handler() and accumulate_handler().

As a result, the kernel will proceed to load the module with corrupted
or incomplete sections, which can lead to unpredictable behavior or
kernel panics.

So we need to check the return values of the handlers to propagate the
error, and fall back to the cleanup mode.

Fixes: 8fd6c51 ("riscv: Add remaining module relocations")
