From f9981bc53825de2c001659d35c870786771f1e90 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 26 Jul 2019 22:19:07 +0200 Subject: 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 Cc: linux-crypto@vger.kernel.org Cc: Herbert Xu Cc: "David S.
