From 62728e82026c90af004dd2c328c1314f2f3e6b58 Mon Sep 17 00:00:00 2001 From: Leilei Zhao Date: Tue, 7 Apr 2015 17:45:06 +0800 Subject: [PATCH] crypto: atmel-sha - 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.
