+ * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
+ *
+ * We have three types of helper function pairs to utilize these locks.
+ *     (Always use the helper functions.)
+ * 1) bcm43xx_{un}lock_noirq():
+ *     Takes bcm->mutex. Does _not_ protect against IRQ concurrency,
+ *     so it is almost always unsafe, if device IRQs are enabled.
+ *     So only use this, if device IRQs are masked.
+ *     Locking may sleep.
+ *     You can sleep within the critical section.
+ * 2) bcm43xx_{un}lock_irqonly():
+ *     Takes bcm->irq_lock. Does _not_ protect against
+ *     bcm43xx_lock_noirq() critical sections.
+ *     Does only protect against the IRQ handler path and other
+ *     irqonly() critical sections.
+ *     Locking does not sleep.
+ *     You must not sleep within the critical section.
+ * 3) bcm43xx_{un}lock_irqsafe():
+ *     This is the cummulative lock and takes both, mutex and irq_lock.
+ *     Protects against noirq() and irqonly() critical sections (and
