Subject: tracing/events: add missing type info of dynamic arrays
X-Git-Tag: upstream/snapshot3+hdmi~16109^2~431
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=68fd60a8c8bca6af51805c45f286f0f2572ac977;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

tracing/events: add missing type info of dynamic arrays

The format file doesn't contain enough information for
__dynamic_array/__string. The type name is missing.

Before:
  # cat format:
  name: irq_handler_entry
  ...
          field:__data_loc name;  offset:16;      size:2;

After:
  # cat format:
  name: irq_handler_entry
  ...
          field:__data_loc char[] name;  offset:16;      size:2;
