Sven Schnelle	ca8c5584e0	facetimehd: add channel waitqueue ... add a per channel waitqueue to be able to have more than one ringbuffer entry in flight. Signed-off-by: Sven Schnelle <svens@stackframe.org>	2015-11-28 22:59:44 +01:00
Sven Schnelle	aebaf60c07	facetimehd: change fthd_channel_ringbuf_send() error handling ... In the current implementation it returns -1 on error, an offset value otherwise. Change it to return a negative error value, and add a pointer to an u32 for receiving the entry offset as an extra argument. This makes the ugly (u32)-1 return code comparision obsolete, and we can return a more detailed error code like EAGAIN if all ringbuffer slots are busy.	2015-11-28 21:18:22 +01:00
