Subject: crypto: simd - convert to use crypto_simd_usable()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8b8d91d4ce5a1497755eb925f4390da48f01076b;p=openwrt%2Fstaging%2Fblogic.git

crypto: simd - convert to use crypto_simd_usable()

Replace all calls to may_use_simd() in the shared SIMD helpers with
crypto_simd_usable(), in order to allow testing the no-SIMD code paths.
