Subject: [PATCH v2 08/12] drivers: export device_is_bound()

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

Export the symbol for device_is_bound() so that we can use it in gpio-sim
to check if the simulated GPIO chip is bound before fetching its driver
data from configfs callbacks in order to retrieve the name of the GPIO
chip device.
