From a1bc07c5205193ff1d771f4ef23402ae1400d42a Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 29 May 2014 19:25:55 +0200 Subject: [PATCH] drm: Don't export internal module variables Drivers really have no business touching these. Noticed because exynose _did_ touch the vblank off delay, which could potentially affect other drivers. drm_debug is an exception since it's used in macros and inline functions. Note that this reduces the timeout on exynos from 50s to 5s. Apparently this was done to paper over a vblank get/put race in exynos, but really should be fixed properly somewhere else. Spotted by David. v2: Drop bonghits changes. Note to self: Don't submit patches before first coffee.
