The changes made for v5.1 to override the default platform_name assumed the card device was properly initialized so that devm_strdup() could be used. This is true for the majority of the machine drivers, but unfortunately this isn't valid for four of the Cherrytrail-based ones which don't follow the same programming flow and initialize the card device last. After hitting a kernel oops on cht-bsw-max98090 (Cyan Chromebook) I found 3 other cases where the same fix is required.
These fixes should be applied for 5.1 and 5.2. While it's not an excuse for this miss, the impact is limited in that the kernel oops will only happen when SOF is used.
