From 4d980939374054b569dca981b1fb8f353c24a0ac Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Fri, 21 Aug 2020 21:53:51 +0200 Subject: block/nvme: Rename local variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We are going to modify the code in the next commit. Renaming the 'resp' variable to 'id' first makes the next commit easier to review. No logical changes.
