Subject: [PATCH v1 1/3] gpiolib: acpi: Add missing memset(0) to acpi_get_gpiod_from_data()
When refactoring the acpi_get_gpiod_from_data() the change missed
cleaning up the variable on stack. Add missing memset().
Reported-by: Ferry Toth <ftoth@...londelft.nl>
Fixes: 16ba046e86e9 ("gpiolib: acpi: teach acpi_find_gpio() to handle data-only nodes")
