Subject: xen/events: Set irq_info->evtchn before binding the channel to CPU in __startup_pirq()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16e6bd5970c88a2ac018b84a5f1dd5c2ff1fdf2c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

xen/events: Set irq_info->evtchn before binding the channel to CPU in __startup_pirq()

.. because bind_evtchn_to_cpu(evtchn, cpu) will map evtchn to
'info' and pass 'info' down to xen_evtchn_port_bind_to_cpu().
