Subject: [PATCH 6/6] mmc: remove the call to check_disk_change
Date: Wed, 8 Jul 2020 14:25:46 +0200 [thread overview]
Message-ID: <20200708122546.214579-7-hch@lst.de> (raw)
In-Reply-To: <20200708122546.214579-1-hch@lst.de>
The mmc driver doesn't support event notifications, which means
that check_disk_change is a no-op.
