+ * An Intel machine driver may be used by many different devices but are
+ * difficult for userspace to differentiate, since machine drivers ususally
+ * use their own name as the card short name and leave the card long name
+ * blank. To differentiate such devices and fix bugs due to lack of
+ * device-specific configurations, this function allows DMI info to be used
+ * as the sound card long name, in the format of
+ * "vendor-product-version-board"
+ * (Character '-' is used to separate different DMI fields here).
+ * This will help the user space to load the device-specific Use Case Manager
+ * (UCM) configurations for the card.
+ *
+ * Possible card long names may be:
+ * DellInc.-XPS139343-01-0310JH
+ * ASUSTeKCOMPUTERINC.-T100TA-1.0-T100TA
+ * Circuitco-MinnowboardMaxD0PLATFORM-D0-MinnowBoardMAX
+ *
+ * This function also supports flavoring the card longname to provide
+ * the extra differentiation, like "vendor-product-version-board-flavor".
+ *
+ * We only keep number and alphabet characters and a few separator characters
+ * in the card long name since UCM in the user space uses the card long names
+ * as card configuration directory names and AudoConf cannot support special
+ * charactors like SPACE.
+ *
+ * Returns 0 on success, otherwise a negative error code.
