[PATCH] drm/i915/gvt: fix memory leak of a cmd_entry struct on error exit path

From: Colin King
Date: Tue Apr 10 2018 - 08:33:28 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The error exit path when a duplicate is found does not kfree and cmd_entry
struct and hence there is a small memory leak. Fix this by kfree'ing it.

Detected by CoverityScan, CID#1370198 ("Resource Leak")

Fixes: be1da7070aea ("drm/i915/gvt: vGPU command scanner")
