| H A D | sev-dev.c | 1f14b57f Tue Mar 03 07:57:23 CST 2020 John Allen <john.allen@amd.com> crypto: ccp - Cleanup misc_dev on sev_exit()
Explicitly free and clear misc_dev in sev_exit(). Since devm_kzalloc()
associates misc_dev with the first device that gets probed, change from
devm_kzalloc() to kzalloc() and explicitly free memory in sev_exit() as
the first device probed is not guaranteed to be the last device released.
To ensure that the variable gets properly set to NULL, remove the local
definition of misc_dev.
