From 9deb6ad661c1656dc770d35336a84b0d885c3ff2 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 6 Aug 2015 09:38:02 -0300 Subject: [PATCH] [media] v4l2: move tracepoint generation into separate file To compile videobuf2-core as a module, the vb2_* tracepoints must be exported from the videodev module. Instead of exporting vb2 tracepoint symbols from v4l2-ioctl.c, move the tracepoint generation into a separate file. This patch fixes the following build error in the modpost stage, introduced by 2091f5181c66 ("[media] videobuf2: add trace events"): ERROR: "__tracepoint_vb2_buf_done" undefined! ERROR: "__tracepoint_vb2_dqbuf" undefined! ERROR: "__tracepoint_vb2_qbuf" undefined! ERROR: "__tracepoint_vb2_buf_queue" undefined!
