stable inclusion from stable-5.10.72 commit 60df9f55562a57173a11b6c7011eee40dfa48157 bugzilla: 182982 https://gitee.com/openeuler/kernel/issues/I4I3L1
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
