Thank you Jiawei. this version LGTM though I am not a Binutils developer. Do Binutils reviewers have thoughts on this new version? Thanks in advance.

Subject:[PATCH v2] RISC-V: Fix disassemble fetch fail return value.
This bug reported in
https://sourceware.org/bugzilla/show_bug.cgi?id=30184 <https://sourceware.org/bugzilla/show_bug.cgi?id=30184 >
And discussed in
https://sourceware.org/pipermail/binutils/2023-February/126213.html <https://sourceware.org/pipermail/binutils/2023-February/126213.html >
We also checked the implementation of return value in arm and mips.
So this patch changes the return value to -1, that can fix bugs and maintain
consistency with other architectures.
opcodes/ChangeLog:
 * riscv-dis.c (print_insn_riscv):Change the return value.
