[PATCH 6.18 223/275] crypto: atmel-ecc - Release client on allocation failure

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: Thorsten Blum <thorsten.blum@linux.dev>

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.
