/* Locking and synchronization:
 *
 * The basic principle is that everything is serialized through a
 * single spinlock, priv->lock.  The lock is used in user, bh and irq
 * context, so when taken outside hardirq context it should always be
 * taken with interrupts disabled.  The lock protects both the
 * hardware and the struct orinoco_private.
 *
 * Another flag, priv->hw_unavailable indicates that the hardware is
 * unavailable for an extended period of time (e.g. suspended, or in
 * the middle of a hard reset).  This flag is protected by the
 * spinlock.  All code which touches the hardware should check the
 * flag after taking the lock, and if it is set, give up on whatever
 * they are doing and drop the lock again.  The orinoco_lock()
 * function handles this (it unlocks and returns -EBUSY if
 * hw_unavailable is non-zero).
