Subject: irqdomain: Add non-hierarchy helper irq_domain_set_info
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5f22f5c668204f3af7557018b2ad6cf2074defac;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

irqdomain: Add non-hierarchy helper irq_domain_set_info

This adds the helper irq_domain_set_info() in a non-domain hierarchy
variant. This allows to use the helper for generic chip since not
all chips using generic chip support domain hierarchy.
