Subject: [PATCH v3 6/7] gpio: mockup: change the signature of unlocked get/set helpers

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

The unlocked variants only get called from places where we already have
the pointer to the underlying gpio_mockup_chip structure, so take it
as parameter instead of struct gpio_chip.
