Subject: libdrm/radeon: Fix section size mismatch to reset the section.
X-Git-Tag: submit/1.0/20121108.012404~306
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1802e1a4e747b5906d3af10c4a53fd457eddcbb4;p=profile%2Fivi%2Flibdrm.git

libdrm/radeon: Fix section size mismatch to reset the section.

If there is section size mismatch reusing the section object
makes section start fail.
Reseting the object before doing error checking prevents the
possible flood of errors.
