* 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.
