In the Linux kernel, the following vulnerability has been resolved:
ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction
Actually check if the passed pointers are valid, before writing to them.
This also fixes a USBAN warning:
UBSAN: invalid-load in ../sound/soc/fsl/imx-card.c:687:25
load of value 255 is not a valid value for type '_Bool'
This is because playback_only is uninitialized and is not written to, as
the playback-only property is absent.
