gpio: Add missing spin_lock_init in gpio-ml-ioh driver

2012-02-02T04:59:37Z

This bug was introduced by commit 54be5663 "gpio-ml-ioh: Support interrupt function" which adds a spinlock to struct ioh_gpio but never init the spinlock. Signed-off-by: Axel Lin Signed-off-by: Grant Likely

gpio/it8761e: Restrict it8761e gpio driver to x86.

2012-01-18T00:43:09Z

This driver does an unconditional read of io space during module init which causes a bad dereference on ARM. It looks to me like this is an x86 only drivers, so restrict it to only compile on x86. Signed-off-by: Grant Likely Cc: Denis Turischev

gpio-ml-ioh: cleanup __iomem annotation usage

2012-01-16T16:12:24Z

The __iomem annotation is to be used together with pointers used in iowrite32() but not for pointers returned by kzalloc(). For more details see [1] and [2]. This patch will remove the following sparse warning (i.e. when copiling with "make C=1"): * warning: incorrect type in assignment (different address spaces) References: [1] A new I/O memory access mechanism (Sep 15, 2004) http://lwn.net/Articles/102232/ [2] Being more anal about iospace accesses (Sep 15, 2004) http://lwn.net/Articles/102240/ Signed-off-by: Márton Németh Signed-off-by: Grant Likely

gpio-ml-ioh: cleanup NULL pointer checking
