If anyone has any objections, please let me know. ------------------ From: Hans Verkuil [ 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'.
