Hello Azael Avalos,

The patch 811be48a6c0e: "toshiba_acpi: Add keyboard backlight
support" from Mar 25, 2014, leads to the following static checker
warning:

	warn: we tested 'ret' before and it was 'false'

drivers/platform/x86/toshiba_acpi.c
  1736          ret = sysfs_create_group(&dev->acpi_dev->dev.kobj,
  1737                                   &toshiba_attr_group);
  1738          if (ret) {
                    ^^^
  1739                  dev->sysfs_created = 0;
  1740                  goto error;
                             ^^^^^
