Subject: [PATCH AUTOSEL 6.5 10/28] media: tuners: qt1010: replace BUG_ON with a regular error
Date: Fri, 8 Sep 2023 20:35:44 -0400 [thread overview]
Message-ID: <20230909003604.3579407-10-sashal@kernel.org> (raw)
In-Reply-To: <20230909003604.3579407-1-sashal@kernel.org>
From: Hans Verkuil <hverkuil-cisco@xs4all.nl>
[ Upstream commit ee630b29ea44d1851bb6c903f400956604834463 ]
BUG_ON is unnecessary here, and in addition it confuses smatch.
Replacing this with an error return help resolve this smatch
warning:
drivers/media/tuners/qt1010.c:350 qt1010_init() error: buffer overflow 'i2c_data' 34 <= 34
