[PATCH v1 1/1] ACPI: docs: gpio-properties: Unify ASL style for GPIO examples

[Andy Shevchenko]

GPIO examples of ASL in the board.rst, enumeration.rst and gpio-properties.rst
are not unified. Unify them for better reader experience.

 The driver might expect to get the right GPIO when it does::
 
   desc = gpiod_get(dev, "reset", GPIOD_OUT_LOW);
+  if (IS_ERR(desc))

 but since there is no way to know the mapping between "reset" and
 the GpioIo() in _CRS desc will hold ERR_PTR(-ENOENT).
