Subject: crypto: aead - Add crypto_aead_set_reqsize helper
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=21b7013414db320be418d5f28f72af5c0665dc18;p=openwrt%2Fstaging%2Fblogic.git

crypto: aead - Add crypto_aead_set_reqsize helper

This patch adds the helper crypto_aead_set_reqsize so that people
don't have to directly access the aead internals to set the reqsize.
