+ * We have three types of helper function pairs to utilize these locks.

+ * 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).

+  This driver exists because the "normal" serial driver doesn't work too well
+  with GSM modems. Issues:
+  - data loss -- one single Receive URB is not nearly enough
+  - nonstandard flow (Option devices) and multiplex (Sierra) control
+  - controlling the baud rate doesn't make sense
+
+  This driver is named "option" because the most common device it's
+  used for is a PC-Card (with an internal OHCI-USB interface, behind
+  which the GSM interface sits), made by Option Inc.
+
+  Some of the "one port" devices actually exhibit multiple USB instances
+  on the USB bus. This is not a bug, these ports are used for different
+  device features.
