Subject: genirq/proc: Use the the accessor to report the effective affinity
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6bc6d4abd22e890cf69a05554fa8f8f83f351515;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

genirq/proc: Use the the accessor to report the effective affinity

If CONFIG_GENERIC_IRQ_EFFECTIVE_AFF_MASK is defined, but that the
interrupt is not single target, the effective affinity reported in
/proc/irq/x/effective_affinity will be empty, which is not the truth.

Instead, use the accessor to report the affinity, which will pick
the right mask.
