Subject: dynamic_debug: Remove unnecessary __used
X-Git-Tag: v3.7-rc3~14^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c0d2af637863940b1a4fb208224ca7acb905c39f;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

dynamic_debug: Remove unnecessary __used

The __used attribute prevents gcc from eliminating
unnecessary, otherwise optimized away, metadata for
debugging logging messages.

Remove the __used attribute.
