From 2e1796fd4904fdd6062a8e4589778ea899ea0c8d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 21 Jul 2023 10:23:42 +0200 Subject: [PATCH] media: pci: cx23885: replace BUG with error return 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'.
