[PATCH 4.9 038/153] tpm_tis: fix the error handling of init_tis()

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

commit 5939eaf4f9d432586dd2cdeea778506471e8088e upstream.

Add the missing platform_driver_unregister() and remove the duplicate
platform_device_unregister(force_pdev) in the error handling case.

Fixes: 00194826e6be ("tpm_tis: Clean up the force=1 module parameter")
