From 80656b67b3988f83edd86a280d9937124fe62050 Mon Sep 17 00:00:00 2001 From: Liu Yuan Date: Wed, 13 Apr 2011 22:14:54 +0200 Subject: [PATCH] block, blk-sysfs: Use the variable directly instead of a function call In the function blk_register_queue(), var _dev_ is already assigned by disk_to_dev().So use it directly instead of calling disk_to_dev() again. Signed-off-by: Liu Yuan Modified by me to delete an empty line in the same function while in there anyway.
