| * i2c: xiic: fix reference leak when pm_runtime_get_sync failsQinglang Miao2021-04-141-2/+2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More and more drivers rely on devres to manage their resources, however if bus' probe() and release() methods are not trivial and control some of resources as well (for example enable or disable clocks, or attach device to a power domain), we need to make sure that driver-allocated resources are released immediately after driver's remove() method returns, and not postponed until driver core gets around to releasing resources. To fix that we open a new devres group before calling driver's probe() and explicitly release it when we return from driver's remove().
