checkpatch reports the following warning on the above:

WARNING: quoted string split across lines
#27: FILE: drivers/crypto/talitos.c:2359:
  				.cra_driver_name = "authenc-hmac-sha1-"
+						   "cbc-aes-talitos-hsna",


But when I fixes the patch as follows, I get another warning:

  		.alg.aead = {

So, how should this be fixed ?

Thanks
Christophe
