From 021a8ca2ba23c01487a98ad23b68ac062e14cf32 Mon Sep 17 00:00:00 2001 From: Keguang Zhang Date: Mon, 25 Sep 2023 20:17:34 +0800 Subject: genirq/generic-chip: Fix the irq_chip name for /proc/interrupts irq_init_generic_chip() only sets the name for the first chip type, which leads to empty names for other chip types. Eventually, these names will be shown as "-" /proc/interrupts. Set the name for all chip types by default.
