From 7c2d748e847695c89427fb23a7d5ab0a04ad2ccc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 9 May 2018 15:59:44 +0200 Subject: [PATCH] memstick: don't call blk_queue_bounce_limit All in-tree host drivers set up a proper dma mask and use the dma-mapping helpers. This means they will be able to deal with any address that we are throwing at them.
