Subject: of/irq: Use of_msi_get_domain instead of open-coded "msi-parent" parsing
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=61c08240a103000b75dcf7ef2cf03d552aa91fa3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

of/irq: Use of_msi_get_domain instead of open-coded "msi-parent" parsing

Now that we have a function that implements the complexity of the
"msi-parent" property parsing, switch to that.
