From: Rikard Falkeborn Date: Tue, 30 Nov 2021 21:40:43 +0000 (+0100) Subject: genirq/generic_chip: Constify irq_generic_chip_ops X-Git-Tag: v5.17-rc1~92^2~16 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4946f15e8c334840bf277a0bf924371eae120fcd;p=thirdparty%2Fkernel%2Flinux.git genirq/generic_chip: Constify irq_generic_chip_ops The only usage of irq_generic_chip_ops is to pass its address to irq_domain_add_linear() which takes a pointer to const struct irq_domain_ops. Make it const to allow the compiler to put it in read-only memory.
