Gregory Nutt d09bb13833 In case a thread is doing a blocking operation (e.g. read()) on a serial ... device, while it is being terminated by pthread_cancel(), then uart_close() gets called, but the semaphore (dev->recv.sem in the above example) is still blocked. This means that once the serial device is opened next time, data will arrive on the serial port (and driver interrupts handled as normal), but the received characters never arrive in the reader thread. This patch addresses the problem by re-initializing the semaphores on the last uart_close() on the device.		2014-12-13 08:07:21 -06:00
