From 4e8e6427319de323f613caa8fd37120df83138d0 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Mon, 6 Sep 2021 17:01:12 +0800 Subject: [PATCH] scsi: sd: Free scsi_disk device via put_device() [ Upstream commit 265dfe8ebbabae7959060bd1c3f75c2473b697ed ] After a device is initialized via device_initialize() it should be freed via put_device(). sd_probe() currently gets this wrong, fix it up.
