Subject: [PATCH v3 2/2] kho: remove unnecessary WARN_ON(err) in kho_populate()
Date: Thu, 12 Feb 2026 11:11:46 +0000	[thread overview]
Message-ID: <20260212111146.210086-3-ranxiaokai627@163.com> (raw)
In-Reply-To: <20260212111146.210086-1-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.
