Subject: crypto: talitos - Correct dst != src case handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=695ad589698571046d42a4450c2d801486905535;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

crypto: talitos - Correct dst != src case handling

Seems that dst == src, but this fixes the logic in case it's not.
