The patch titled platform: add new device registration helper has been removed from the -mm tree. Its filename was platform-add-new-device-registration-helper.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: platform: add new device registration helper From: Dmitry Baryshkov <dbaryshkov@xxxxxxxxx> Add a helper that registers simple platform_device w/o resources but with parent and device data. This is usefull to cleanup platform code from code that registers such simple devices as leds-gpio, generic-bl, etc. Signed-off-by: Dmitry Baryshkov <dbaryshkov@xxxxxxxxx> Cc: Greg KH <greg@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/base/platform.c | 47 ++++++++++++++++++++++++++++++ include/linux/platform_device.h | 2 + 2 files changed, 49 insertions(+) diff -puN drivers/base/platform.c~platform-add-new-device-registration-helper drivers/base/platform.c --- a/drivers/base/platform.c~platform-add-new-device-registration-helper +++ a/drivers/base/platform.c @@ -391,6 +391,53 @@ error: } EXPORT_SYMBOL_GPL(platform_device_register_simple); +/** + * platform_device_register_data + * @parent: parent device for the device we're adding + * @name: base name of the device we're adding + * @id: instance id + * @data: platform specific data for this platform device + * @size: size of platform specific data + * + * This function creates a simple platform device that requires minimal + * resource and memory management.
