[ Upstream commit 3cc393d2232ec770b5f79bf0673d67702a3536c3 ]
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.
