crypto: api - Remove redundant #ifdef in crypto_yield()
While looking at CONFIG_PREEMPT dependencies treewide the #ifdef in crypto_yield() matched. CONFIG_PREEMPT and CONFIG_PREEMPT_VOLUNTARY are mutually exclusive so the extra !CONFIG_PREEMPT conditional is redundant. cond_resched() has only an effect when CONFIG_PREEMPT_VOLUNTARY is set, otherwise it's a stub which the compiler optimizes out. Remove the whole conditional. No functional change. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: linux-crypto@vger.kernel.org Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: "David S.
