If anyone has any objections, please let me know. ------------------ From: Thorsten Blum commit 095d50008d55d13f8fcf1bbeb7c6eba51779bc85 upstream. Call atmel_ecc_i2c_client_free() to release the I2C client reserved by atmel_ecc_i2c_client_alloc() when crypto_alloc_kpp() fails. Otherwise ->tfm_count will be out of sync.
