[ Upstream commit ca1438dcb34c7fcad63b6ce14ea63a870b92a69b ]
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.
