crypto: akcipher - pass instance to crypto_grab_akcipher()
Initializing a crypto_akcipher_spawn currently requires: 1. Set spawn->base.inst to point to the instance. 2. Call crypto_grab_akcipher(). But there's no reason for these steps to be separate, and in fact this unneeded complication has caused at least one bug, the one fixed by commit 6db43410179b ("crypto: adiantum - initialize crypto_spawn::inst") So just make crypto_grab_akcipher() take the instance as an argument. To keep the function call from getting too unwieldy due to this extra argument, also introduce a 'mask' variable into pkcs1pad_create(). Signed-off-by: Eric Biggers <> Signed-off-by: Herbert Xu <>
