*	serdev: Do not call .receive_buf() callback recursively	Andrey Smirnov	2019-05-15	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \|	Code implementing .receive_buf() callback can potentially call serdev_device_write(), which will call serdev_device_poller(). We need to make sure that such a call is a no-op in order to prevent corrupting shared data buffer as well as breaking .receive_buf callback that most likely does not expect that to happen.
