Tadeusz Struk a430e67d9a tpm: Handle negative priv->response_len in tpm_common_read() 
The priv->response_length can hold the size of an response or an negative
error code, and the tpm_common_read() needs to handle both cases correctly.
Changed the type of response_length to signed and accounted for negative
value in tpm_common_read().
