From 4846c4c17e292537d4fedd9995432d3a0d78d355 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Tue, 15 Oct 2024 12:09:44 -0700 Subject: [PATCH] serial: 8250: 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.
