SubjectRe: [PATCH v4 0/2] thermal: rcar_gen3_thermal: fix IRQ issues
Hi Jiada,

I think this series looks good. Unfortunately I'm out of office for the
next week and are thus unable to test it. Please don't let this block
this series but if it's still on the ML when I'm back I will do a proper
review and test of it.
