Subject: [PATCH] irqchip/stm32: fix return value of stm32_exti_h_set_affinity
Date: Fri, 12 Jun 2020 09:29:01 +0200 [thread overview]
Message-ID: <20200612072901.14388-1-ludovic.barre@st.com> (raw)
exti hardware point of view, there is no specific action on set_affinity.
So the affinity must be forwarded to parent if there is a
descendent irqchips, otherwise just return IRQ_SET_MASK_OK_DONE.
