gpio: lock device when calling device_is_bound()

[PATCH 0/3] gpio: lock device when calling device_is_bound()

Posted by Bartosz Golaszewski 6 days, 19 hours ago

The kerneldoc for device_is_bound() says it must be called with the
device lock taken. Add missing synchronization to GPIO modules using it.
