Subject[PATCH -next] viper_tpm_init(): fix memleak on registration failure
Date
In case device registration fails, the platform device
structure needs to be free. Use platform_device_put()
to free all resources instead of using kfree to release
the platform device.

Fixes: 352699a3d7cc ("Basic support for the Arcom/Eurotech Viper SBC.")
