From 1d1b91637ce1d0968d17b0a288de557946a9494e Mon Sep 17 00:00:00 2001 From: Leilei Zhao Date: Tue, 7 Apr 2015 17:45:08 +0800 Subject: [PATCH] crypto: atmel-tdes - 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.
