Subject: trace: remove pipe_resource wrapping
X-Git-Tag: upstream/17.1.0~1926
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d17b8d08a3e51df7ff218adf54600b34fa015a4f;p=platform%2Fupstream%2Fmesa.git

trace: remove pipe_resource wrapping

Not needed. ddebug does the same thing. The limitation is that drivers
can only use pipe_resource::screen through pipe_resource_reference.

This unbreaks trace, because pipe_context uploaders aren't wrapped,
so trace doesn't understand buffers returned by them.
