[PATCH v2 08/29] crypto: skcipher - call cond_resched() directly

From: Eric Biggers
Date: Sun Dec 29 2024 - 19:20:21 EST


From: Eric Biggers <ebiggers@xxxxxxxxxx>

In skcipher_walk_done(), instead of calling crypto_yield() which
requires a translation between flags, just call cond_resched() directly.
This has the same effect.
