From 1454f894ff0df7eb3021584f0d1c1baa70444da5 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Sat, 7 Jun 2014 12:02:56 +1000 Subject: [PATCH] st/mesa: remove extra calculation of sampler count This code was originally introduced to fix https://bugs.freedesktop.org/show_bug.cgi?id=53617. The comment says you need to pass NULL in order to unref old views however cso_set_sampler_views() already takes care of old views with the second for loop. Also as of 2355a6441435b8e66a032c44f0794066338e30a3 cso_set_sampler_views() passes the max of the old and new views to the driver for all state trackers making this code obsolete.
