Subject: [PATCH -next 2/2] kho: remove unnecessary WARN_ON(err) in kho_populate()
Date: Fri, 6 Feb 2026 04:31:21 +0000 [thread overview]
Message-ID: <20260206043121.197564-3-ranxiaokai627@163.com> (raw)
In-Reply-To: <20260206043121.197564-1-ranxiaokai627@163.com>
From: Ran Xiaokai <ran.xiaokai@zte.com.cn>
The following pr_warn() provides detailed error and location
information, WARN_ON(err) adds no additional debugging value,
so remove the redundant WARN_ON() call.
