Split hotkey_get/set into hotkey_status_get/set and hotkey_mask_get/set; 2. Cache the status of hot key mask for later driver use; 3. Make sure the cache of hot key mask is refreshed when needed; 4. log a printk notice when the firmware doesn't set the hot key mask to exactly what we asked it to; 5. Add proper locking to the data structures. Only (4) should be user-noticeable, but there is a chance (5) fixes some unknown/unreported race conditions.
