Subject: [CRYPTO]: Initialize TCRYPT on-stack scatterlist objects correctly.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b733588559fc13547a59ccf81651c775b8f2719c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[CRYPTO]: Initialize TCRYPT on-stack scatterlist objects correctly.

Use sg_init_one() and sg_init_table() as needed.
