Fix spelling across comments (besides obvious grammar issues): - spell words in full, e.g., 'img' --> 'image' - refer to 'gpio-keys' consistently - refer to acpi_power_off() clearly as to function - make sure that the first line is only for the affected model(s) - miscellaneous improvements Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Link: https://lore.kernel.org/r/20240902150625.2722187-1-andriy.shevchenko@linux.intel.com Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
