linux/random.h, linux/sizes.h, linux/cdev.h, linux/fs.h, and linux/workqueue.h are not used anywhere in this file; none of their symbols appear in the source, and none are needed transitively either (debugfs helpers come from linux/debugfs.h, the async worker uses kthread_run()/kthread_stop() rather than the workqueue API).

Verified by removing the five includes and rebuilding drivers/staging/greybus out-of-tree with W=1: no new warnings or errors, and checkpatch.pl reports the same warning/check count before and after.
