+ *
+ * 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.

+ *
+ * At time=0
+ *  PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ *  BD  | 0 | 1 | 2 | 3 |
+ *
+ * At time=1 (period elapsed)
+ *  PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ *  BD      | 1 | 2 | 3 | 0 |
+ *
+ * At time=2 (second period elapsed)
+ *  PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ *  BD          | 2 | 3 | 0 | 1 |
+ *
+ * The bd_head field points to the index of the BD to be read.  It's also the
+ * position to be filled at next.  The pcm_head and the pcm_filled fields
+ * point to the indices of the current position and of the next position to
+ * be filled, respectively.  For PCM buffer there are both _head and _filled
+ * because they may be difference when nperiods > 4.  For example, in the
+ * example above at t=1, bd_head=1 and pcm_head=1 while pcm_filled=5:
+ *
+ * pcm_head (=1) --v               v-- pcm_filled (=5)
+ *       PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ *       BD      | 1 | 2 | 3 | 0 |
+ *  bd_head (=1) --^               ^-- next to fill (= bd_head)
+ *
+ * For nperiods < 4, the remaining BDs out of 4 are marked as invalid, so that
+ * the hardware skips those BDs in the loop.
+ *
+ * An exceptional setup is the case with nperiods=1.  Since we have to update
+ * BDs after finishing one BD processing, we'd need at least two BDs, where
+ * both BDs point to the same content, the same address, the same size of the
+ * whole PCM buffer.
