Subject: crypto: aes-generic - unexport last-round AES tables
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1e25ca02a0619c10bc0eae975846926902381ce5;p=linux.git

crypto: aes-generic - unexport last-round AES tables

The versions of the AES lookup tables that are only used during the last
round are never used outside of the driver, so there is no need to
export their symbols.
