Subject: drm/vc4: Use drm_free_large() on handles to match its allocation.
X-Git-Tag: v4.7.4~38
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ae2ba7afed02d9ff0f0473bfb8d1971a75910cb;p=thirdparty%2Fkernel%2Fstable.git

drm/vc4: Use drm_free_large() on handles to match its allocation.

commit d5fb46e0e3b7e49ee83ba92efc3ab4e1a545ecc1 upstream.

If you managed to exceed the limit to switch to vmalloc, we'd use the
wrong free.
