Subject: crypto: chacha20 - Remove cra_alignmask
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a1c73383c032ea467c4e766d4471edf91cf384cb;p=linux.git

crypto: chacha20 - Remove cra_alignmask

Now that crypto_chacha20_setkey() and crypto_chacha20_init() use the
unaligned access macros and crypto_xor() also accepts unaligned buffers,
there is no need to have a cra_alignmask set for chacha20-generic.
