From 8a10eb8d36ffc86512ae66a35c8888f07b8ec921 Mon Sep 17 00:00:00 2001 From: Leilei Zhao Date: Tue, 7 Apr 2015 17:45:09 +0800 Subject: crypto: atmel-aes - initialize spinlock in probe Kernel will report "BUG: spinlock lockup suspected on CPU#0" when CONFIG_DEBUG_SPINLOCK is enabled in kernel config and the spinlock is used at the first time. It's caused by uninitialized spinlock, so just initialize it in probe.
