+Subject: [PATCH] scsi: fix the dma_max_mapping_size call
+Date: Mon, 22 Jul 2019 11:20:38 +0200
+Message-Id: <20190722092038.17659-1-hch@lst.de>
+X-Mailer: git-send-email 2.20.1
+MIME-Version: 1.0
+X-SRS-Rewrite: SMTP reverse-path rewritten from <hch@infradead.org> by
+ bombadil.infradead.org. See http://www.infradead.org/rpr.html
+Sender: linux-scsi-owner@vger.kernel.org

+X-Virus-Scanned: ClamAV using ClamSMTP
+
+We should only call dma_max_mapping_size for devices that have a DMA
+mask set, otherwise we can run into a NULL pointer dereference that
+will crash the system.
+
+Also we need to do right shift to get the sectors from the size in
+bytes, not a left shift.
+
+Fixes: bdd17bdef7d8 ("scsi: core: take the DMA max mapping size into account")
