The original driver lock with spin_lock_irqsave()/spin_unlock_irqrestore() because of it's maybe used in interrupt context f81232_process_read_urb(). We had remove it from previous patch "implement RX bulk-in EP", so we can change it from busying loop spin_lock to sleepable mutex_lock. Signed-off-by:
