From 05efeebd2838f0dedf765179244a7fb543fdca8a Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 18 Mar 2014 16:26:25 +0100 Subject: [PATCH] drm/i915: Fix up the forcewake timer initialization This is a regression introduced in commit 0294ae7b44bba7ab0d4cef9a8736287f38bdb4fd Author: Chris Wilson Date: Thu Mar 13 12:00:29 2014 +0000 drm/i915: Consolidate forcewake resetting to a single function The reordered setup sequence ended up calling del_timer_sync before the timer was set up correctly, resulting in endless hilarity when loading the driver. Compared to Ben's patch (which moved around the setup_timer call to sanitize_early) this moves the sanitize_early call around in the driver load call. This way we avoid calling setup_timer again in the resume code (where we also call sanitize_early).
