If anyone has any objections, please let me know. ------------------ From: Dan Murphy commit f214ff521fb1f861c8d7f7d0af98b06bf61b3369 upstream. Per Jonathan Cameron, the buffer needs to allocate room for a 64 bit timestamp as well as the channels. Change the buffer to allocate this additional space.
