Subject: serial: cpm_uart: Switch to irq_get_nr_irqs()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b9b5df2986c1195504a0c8d1c44691ec099815df;p=users%2Fjedix%2Flinux-maple.git

serial: cpm_uart: Switch to irq_get_nr_irqs()

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.
