| Subject: spi: export tracepoint symbols to modules |
| |
| [ 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. |
| |
| Fixes: f3fdea3af405 ("spi: mxs: add tracing to custom .transfer_one_message callback") |
