X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9f2135419ffb7601b6642147ae0e6ccc19a7d5be;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

irqchip/vic: Consolidate chained IRQ handler install/remove

Chained irq handlers usually set up handler data as well. We now have
a function to set both under irq_desc->lock. Replace the two calls
with one.

Search and conversion was done with coccinelle:
