From a20eefaee64610541d125cd2c10fa25e278f0bee Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 26 Jul 2019 13:22:14 +0200 Subject: [PATCH] staging: most: Use DEFINE_SPINLOCK() instead of struct spinlock For spinlocks the type spinlock_t should be used instead of "struct spinlock".
