From ca1438dcb34c7fcad63b6ce14ea63a870b92a69b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 21 Mar 2019 13:42:25 +0100 Subject: [PATCH] spi: export tracepoint symbols to modules 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.
