Subject: [PATCH] x86/traps: add CONFIG_BUG to the use of __warn()
Date: Mon, 25 Apr 2022 13:59:35 +0800 [thread overview]
Message-ID: <20220425055935.458583-1-starzhangzsd@gmail.com> (raw)
From: zhangshida <zhangshida@kylinos.cn>
__warn() is declared when CONFIG_BUG is defined, so add
CONFIG_BUG when used.
