commit ead3db62bf10fe143bec99e7b7ff370d7a6d23ef ("dm ioctl: do not directly deference user memory in check_version()")

With your commit, we found the following message in stderr:

Command failed

To reproduce:

        git clone git://git.kernel.org/pub/scm/linux/kernel/git/wfg/lkp-tests.git
        cd lkp-tests
        bin/lkp install job.yaml  # job file is attached in this email
        bin/lkp run     job.yaml
