From 842ea771c38a3f0f78bdb1b4d47881e6a210fc15 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 31 Mar 2008 10:03:41 +0900 Subject: [PATCH] [SCSI] bsg: remove minor in struct bsg_device minor in struct bsg_device is used as identifier to find the corresponding struct bsg_device_class. However, request_queuse can be used as identifier for that and the minor in struct bsg_device is unnecessary.
