Subject: s390/PCI: Remove superfluous check of MSI type
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=57b7cb024422bbe85366ef28f5e192997bd16943;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

s390/PCI: Remove superfluous check of MSI type

arch_setup_msi_irqs() hook can only be called from the generic MSI code
which ensures correct MSI type parameter.
