From 762c29164e2850d8c5e4c258cef0077b2584d111 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Fri, 27 Aug 2010 16:41:56 +0000 Subject: [PATCH] econet: kill unnecessary spin_lock_init() The spinlock aun_queue_lock is initialized statically. It is unnecessary to initialize by spin_lock_init() at module load time. This is detected by the semantic patch. // @def@ declarer name DEFINE_SPINLOCK; identifier spinlock; @@ DEFINE_SPINLOCK(spinlock); @@ identifier def.spinlock; @@ - spin_lock_init(&spinlock); // Signed-off-by: Akinobu Mita Cc: Julia Lawall Cc: "David S.
