From: Matthew Wilcox Date: Tue, 20 Dec 2011 16:04:12 +0000 (-0500) Subject: NVMe: Change get_nvmeq to take a dev instead of a namespace X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=040a93b52a9eee8177ebaf2ba0ee0f9f518d1bf8;p=linux-beck.git NVMe: Change get_nvmeq to take a dev instead of a namespace Upcoming patches require calling get_nvmeq when we don't have a namespace. Some callers already have the device in a local variable anyway.
