Message-ID: <1428399911-23325-8-git-send-email-leilei.zhao@atmel.com> Date: Tue, 7 Apr 2015 17:45:08 +0800 From: Leilei Zhao <leilei.zhao@...el.com> To: <herbert@...dor.apana.org.au>, <davem@...emloft.net>, <linux-crypto@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <nicolas.ferre@...el.com>, <Ludovic.Desroches@...el.com> CC: <linux-arm-kernel@...ts.infradead.org>, Leilei Zhao <leilei.zhao@...el.com> Subject: [PATCH 07/10] 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.
