Subject: [PATCH AUTOSEL 5.15 09/19] media: pci: cx23885: replace BUG with error return
Date: Fri,  8 Sep 2023 20:38:53 -0400	[thread overview]
Message-ID: <20230909003903.3580394-9-sashal@kernel.org> (raw)
In-Reply-To: <20230909003903.3580394-1-sashal@kernel.org>

From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

[ Upstream commit 2e1796fd4904fdd6062a8e4589778ea899ea0c8d ]

It was completely unnecessary to use BUG in buffer_prepare().
Just replace it with an error return. This also fixes a smatch warning:

drivers/media/pci/cx23885/cx23885-video.c:422 buffer_prepare() error: uninitialized symbol 'ret'.
