From 1ce7dd26e0f0e34bb75ec56f7f546151af34fcf9 Mon Sep 17 00:00:00 2001 From: Luiz Fernando Capitulino Date: Fri, 24 Mar 2006 17:12:31 -0300 Subject: [PATCH] USB serial: Converts port semaphore to mutexes. The usbserial's port semaphore used to synchronize serial_open() and serial_close() are strict mutexes, convert them to the mutex implementation.
