 Usually there is a certain number of IRQs available.
 How many IRQs there are is hardware-dependent.
 
-The flags can be used for specify behaviors of the IRQ.
+The flags can be used to specify behaviors of the IRQ.
 For example, use \cpp|IRQF_SHARED| to indicate you are willing to share the IRQ with other interrupt handlers (usually because a number of hardware devices sit on the same IRQ); use the \cpp|IRQF_ONESHOT| to indicate that the IRQ is not reenabled after the handler finished.
 It should be noted that in some materials, you may encounter another set of IRQ flags named with the \cpp|SA| prefix.
 For example, the \cpp|SA_SHIRQ| and the \cpp|SA_INTERRUPT|.
