[DRIVER MODEL] Improved dynamically allocated platform_device interface
Re-jig the simple platform device support to allow private data to be attached to a platform device, as well as allowing the parent device to be set. Example usage: pdev = platform_device_alloc("mydev", id); if (pdev) { err = platform_device_add_resources(pdev, &resources, ARRAY_SIZE(resources)); if (err == 0) err = platform_device_add_data(pdev, &platform_data, sizeof(platform_data)); if (err == 0) err = platform_device_add(pdev); } else { err = -ENOMEM; } if (err) platform_device_put(pdev); Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
