From e5babdf928e5d0c432a8d4b99f20421ce14d1ab6 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 28 May 2015 10:22:10 +0200 Subject: mtd: dc21285: use raw spinlock functions for nw_gpio_lock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit bd31b85960a7 (which is in 3.2-rc1) nw_gpio_lock is a raw spinlock that needs usage of the corresponding raw functions. This fixes: drivers/mtd/maps/dc21285.c: In function 'nw_en_write': drivers/mtd/maps/dc21285.c:41:340: warning: passing argument 1 of 'spinlock_check' from incompatible pointer type spin_lock_irqsave(&nw_gpio_lock, flags); In file included from include/linux/seqlock.h:35:0, from include/linux/time.h:5, from include/linux/stat.h:18, from include/linux/module.h:10, from drivers/mtd/maps/dc21285.c:8: include/linux/spinlock.h:299:102: note: expected 'struct spinlock_t *' but argument is of type 'struct raw_spinlock_t *' static inline raw_spinlock_t *spinlock_check(spinlock_t *lock) ^ drivers/mtd/maps/dc21285.c:43:25: warning: passing argument 1 of 'spin_unlock_irqrestore' from incompatible pointer type spin_unlock_irqrestore(&nw_gpio_lock, flags); ^ In file included from include/linux/seqlock.h:35:0, from include/linux/time.h:5, from include/linux/stat.h:18, from include/linux/module.h:10, from drivers/mtd/maps/dc21285.c:8: include/linux/spinlock.h:370:91: note: expected 'struct spinlock_t *' but argument is of type 'struct raw_spinlock_t *' static inline void spin_unlock_irqrestore(spinlock_t *lock, unsigned long flags) Fixes: bd31b85960a7 ("locking, ARM: Annotate low level hw locks as raw") Signed-off-by: Uwe Kleine-König Signed-off-by: Brian Norris --- drivers/mtd/maps/dc21285.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/mtd/maps') diff --git a/drivers/mtd/maps/dc21285.c b/drivers/mtd/maps/dc21285.c index f8a7dd14cee0..70a3db3ab856 100644 --- a/drivers/mtd/maps/dc21285.c +++ b/drivers/mtd/maps/dc21285.c @@ -38,9 +38,9 @@ static void nw_en_write(void) * we want to write a bit pattern XXX1 to Xilinx to enable * the write gate, which will be open for about the next 2ms. */ - spin_lock_irqsave(&nw_gpio_lock, flags); + raw_spin_lock_irqsave(&nw_gpio_lock, flags); nw_cpld_modify(CPLD_FLASH_WR_ENABLE, CPLD_FLASH_WR_ENABLE); - spin_unlock_irqrestore(&nw_gpio_lock, flags); + raw_spin_unlock_irqrestore(&nw_gpio_lock, flags); /* * let the ISA bus to catch on... -- cgit v1.2.3
