-/* *** THEORY OF LOCKING ***
- *
- * We have two different locks in the bcm43xx driver.
- * => bcm->mutex: General sleeping mutex. Protects struct bcm43xx_private
- * and the device registers. This mutex does _not_ protect
- * against concurrency from the IRQ handler.
- * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
- *
- * Please note that, if you only take the irq_lock, you are not protected
- * against concurrency from the periodic work handlers.
- * Most times you want to take _both_ locks.
