Anton Vorontsov 1a02d59aba kfifo: Make kfifo_initialized work after kfifo_free ... After kfifo rework it's no longer possible to reliably know if kfifo is usable, since after kfifo_free(), kfifo_initialized() would still return true. The correct behaviour is needed for at least FHCI USB driver. This patch fixes the issue by resetting the kfifo to zero values (the same approach is used in kfifo_alloc() if allocation failed).
