crypto: atmel-ecc - fix signed integer to u8 assignment
static checker warning: drivers/crypto/atmel-ecc.c:281 atmel_ecdh_done() warn: assigning (-22) to unsigned variable 'status' Similar warning can be raised in atmel_ecc_work_handler() when atmel_ecc_send_receive() returns an error. Fix this too. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
