Subject: [PATCH 2/7] mmc: meson-gx: ack only raised irq
Date: Wed, 17 Apr 2019 22:43:50 +0200 [thread overview]
Message-ID: <20190417204355.469-3-jbrunet@baylibre.com> (raw)
In-Reply-To: <20190417204355.469-1-jbrunet@baylibre.com>
This is merely a clean up. It makes sense to only ack raised irqs
instead of acking everything all the time.
