As the err value is not used unless there was an error it can be assigned conditionally here.
Signed-off-by: Nicholas Mc Guire <der.herr@hofr.at> ---
Not sure if this is really relevant and worth changing, effectively it is practically no change as gcc would move the err = PTR_ERR(simd); below unregister_simds: anyway (based on inspection of .lst/.s files) - so it is more of an adjust C-level to object level for readability.
Patch was compile-tested with multi_v7_defconfig (implies CONFIG_CRYPTO_AES_ARM_CE=m)
Patch is against 4.10-rc7 (localversion-next is next-20170208)
