Subject: [CRYPTO]: HMAC needs some more scatterlist fixups.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a6767721a563acb172c73f693fcf719b3b3d6716;p=linux-beck.git

[CRYPTO]: HMAC needs some more scatterlist fixups.

hmac_setkey(), hmac_init(), and hmac_final() have
a singular on-stack scatterlist.  Initialit is
using sg_init_one() instead of using sg_set_buf().
