[ Upstream commit ce3c2433b074eb9d569a0f63a15d6fd5dbc87f02 ]
Restore a default case to prepare_vdi_in_buffers() to fix the following smatch errors:
drivers/staging/media/imx/imx-media-vdic.c:236 prepare_vdi_in_buffers() error: uninitialized symbol 'prev_phys'. drivers/staging/media/imx/imx-media-vdic.c:237 prepare_vdi_in_buffers() error: uninitialized symbol 'curr_phys'. drivers/staging/media/imx/imx-media-vdic.c:238 prepare_vdi_in_buffers() error: uninitialized symbol 'next_phys'.
Fixes: 6e537b58de772 ("media: imx: vdic: rely on VDIC for correct field order")
