- * 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
- * the IRQ handler path).
- * Locking may sleep.
- * You must not sleep within the critical section.
