Subject: [PATCH] gpio: mockup: initialize a managed pointer in place

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

The preferred pattern for autopointers is to initialize them when they're
declared unless it doesn't make sense. Move the declaration of the
managed device pointer to where it's initialized.
