mtd: dc21285: use raw spinlock functions for nw_gpio_lock

2015-05-28T19:01:29Z

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

mtd: Allow compile test of GPIO consumers if !GPIOLIB

2015-05-20T22:50:24Z

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate. Signed-off-by: Geert Uytterhoeven Cc: David Woodhouse Cc: linux-mtd@lists.infradead.org Signed-off-by: Brian Norris

mtd: maps: sa1100-flash: remove incorrect __exit markups

2015-03-31T00:50:40Z

Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Signed-off-by: Dmitry Torokhov Signed-off-by: Brian Norris

mtd: replace CONFIG_8xx by CONFIG_PPC_8xx

2015-03-31T00:50:40Z

Two config options exist to define powerpc MPC8xx: * CONFIG_PPC_8xx * CONFIG_8xx In addition, CONFIG_PPC_8xx also defines CONFIG_CPM1 as communication co-processor arch/powerpc/platforms/Kconfig.cputype has contained the following comment about CONFIG_8xx item for some years: "# this is temp to handle compat with arch=ppc" It looks like not many places still have that old CONFIG_8xx used, so it is likely to be a good time to get rid of it completely ?

mtd: physmap_of: Add read-only fallback

2015-01-10T07:22:40Z

Previously, when probing a CFI chip which was write-protected at the hardware level, the probe would fail due to the fact it could not put the chip into QUERY mode. This would result in no MTD devices being created. Add a fallback to probe using the map_rom driver if the user-selected probe fails.
