Prarit Bhargava 7e700d2c59 acpi/nfit: Fix memory corruption/Unregister mce decoder on failure ... nfit_init() calls nfit_mce_register() on module load. When the module load fails the nfit mce decoder is not unregistered. The module's memory is freed leaving the decoder chain referencing junk. This will cause panics as future registrations will reference the free'd memory. Unregister the nfit mce decoder on module init failure. [v2]: register and then unregister mce handler to avoid losing mce events [v3]: also cleanup nfit workqueue Fixes: 6839a6d96f ("nfit: do an ARS scrub on hitting a latent media error") Cc: <stable@vger.kernel.org> Cc: "Rafael J.
