Subject: [PATCH v1] LoongArch: Remove dead code in relocate_new_kernel
Date:   Tue, 19 Sep 2023 17:07:08 +0800
Message-Id: <1695114428-20308-1-git-send-email-yangtiezhu@loongson.cn>
Precedence: bulk

The initial aim is to silence the following objtool warning:

arch/loongarch/kernel/relocate_kernel.o: warning: objtool: relocate_new_kernel+0x74: unreachable instruction

There are two adjacent "b" instructions, the second one is unreachable,
it is dead code, just remove it.
