Subject: gpiolib: acpi: Add missing memset(0) to acpi_get_gpiod_from_data()
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
commit 479ac419206b5fe4ce4e40de61ac3210a36711aa upstream.
When refactoring the acpi_get_gpiod_from_data() the change missed
cleaning up the variable on stack. Add missing memset().
