From 4c8d062186d9923c09488716b2fb1b829b5b8006 Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Mon, 23 Dec 2019 00:20:44 -0800 Subject: random: Don't wake crng_init_wait when crng_init == 1 crng_init_wait is only used to wayt for crng_init to be set to 2, so there's no point to waking it when crng_init is set to 1. Remove the unnecessary wake_up_interruptible() call.
