From 32f68cc58c1f3b7a5cb102e55b9987336a1c2770 Mon Sep 17 00:00:00 2001 From: Johann Date: Tue, 31 Jan 2017 15:05:51 -0800 Subject: [PATCH] deblock: annotate postproc parameters Clears a clang static analyzer warning where 'cols' is assumed to be less than 0, preventing the for loop from executing. The assembly already requires that the size be 8 or 16 (U/V or Y plane) and cols is a multiple of 8.
