Subject: irqdomain: Convert domain creation functions to irq_domain_instantiate()
X-Git-Tag: v6.11-rc1~75^2~35
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ada5ed6ecac06e32defe39b15b33e9a6b004413;p=thirdparty%2Fkernel%2Flinux.git

irqdomain: Convert domain creation functions to irq_domain_instantiate()

Domain creation functions use __irq_domain_add(). With the introduction
of irq_domain_instantiate(), __irq_domain_add() becomes obsolete.

In order to fully remove __irq_domain_add(), convert domain
creation function to irq_domain_instantiate()
