From cc4b8dfc3ff32f890cd5de0ce22de44f124d0d05 Mon Sep 17 00:00:00 2001 From: Mithlesh Thukral Date: Wed, 25 Mar 2009 15:51:14 +0530 Subject: [PATCH] Staging: sxg: Fix sleep in atomic context warning while loading driver Leave a spinlock before calling request_irq(). request_irq() calls kmalloc which can sleep. This was generating a warning dump while driver is loaded.
