Subject: serial: amba-pl011: Switch to irq_get_nr_irqs()
X-Git-Tag: v6.13-rc1~173^2~27
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d1a9a2f4ca62c35cc0ffab653241ef686a6a7526;p=thirdparty%2Fkernel%2Flinux.git

serial: amba-pl011: 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.
