Subject: Remove compiler warning by ensure prvInitialiseMutex() is not included if configUSE_M... 
X-Git-Tag: V9.0.0~26
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a02f41f5dc840f259b30ab8658ad835f1fd24f46;p=freertos

Remove compiler warning by ensure prvInitialiseMutex() is not included if configUSE_MUTEXES is 0.
Reduce the number of xTaskCreateStatic() parameters by having the function return the task handle, rather than pass the task handle out using a parameter.  This is also consistent with other objectCreate() functions.
