spi: export tracepoint symbols to modules
[ Upstream commit ca1438dc ] The newly added tracepoints in the spi-mxs driver cause a link error when the driver is a loadable module: ERROR: "__tracepoint_spi_transfer_stop" [drivers/spi/spi-mxs.ko] undefined! ERROR: "__tracepoint_spi_transfer_start" [drivers/spi/spi-mxs.ko] undefined! I'm not quite sure where to put the export statements, but directly after the inclusion of the header seems as good as any other place.
