Subject: [PATCH v5 3/4] media: chips-media: wave5: Add WARN_ON to check if dec_output_info is NULL
Date: Mon, 22 Sep 2025 14:52:54 +0900	[thread overview]
Message-ID: <20250922055255.116-4-jackson.lee@chipsnmedia.com> (raw)
In-Reply-To: <20250922055255.116-1-jackson.lee@chipsnmedia.com>

From: Jackson Lee <jackson.lee@chipsnmedia.com>

The dec_output_info should not be a null pointer, WARN_ON around it to
indicates a driver issue.
