Joe Hattori 5d8e2971e8 char: tpm: Fix possible memory leak in tpm_bios_measurements_open()
In tpm_bios_measurements_open(), get_device() is called on the device
embedded in struct tpm_chip. In the error path, however, put_device() is
not called. This results in a reference count leak, which prevents the
device from being properly released. This commit makes sure to call
put_device() when the seq_open() call fails.
