[v3] Reduce the scope of 'nr_irqs'

[PATCH v3 17/22] serial: ucc_uart: Switch to irq_get_nr_irqs()

Posted by Bart Van Assche 1 month, 1 week ago

Use the irq_get_nr_irqs() function instead of the global variable
'nr_irqs'. Prepare for changing 'nr_irqs' from an exported global
variable into a variable with file scope.
