From 1c90836f70f9a8ef7b7ad9e1fdd8961903e6ced6 Mon Sep 17 00:00:00 2001 From: Avri Altman Date: Tue, 21 May 2019 11:24:22 +0300 Subject: scsi: ufs: Check that space was properly alloced in copy_query_response struct ufs_dev_cmd is the main container that supports device management commands. In the case of a read descriptor request, we assume that the proper space was allocated in dev_cmd to hold the returning descriptor. This is no longer true, as there are flows that doesn't use dev_cmd for device management requests, and was wrong in the first place.
