Subject: [PATCH 3/6] mt76: mt7615: only clear unmasked interrupts in irq tasklet
Date: Mon, 10 Aug 2020 10:58:29 +0200	[thread overview]
Message-ID: <20200810085832.65662-3-nbd@nbd.name> (raw)
In-Reply-To: <20200810085832.65662-1-nbd@nbd.name>

If an interrupt is temporarily masked, its pending events need to be processed
later, even if another interrupt happened in the mean time.
