From b149cbfeecaa2b2870d2c4f878382a024e6e4975 Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Wed, 6 Nov 2019 14:41:15 -0500 Subject: [PATCH] drm/mst: Fix up u64 division MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Change rem_nsec to u32 since that's what do_div returns, this avoids the u64 divide in the drm_print args. Changes in v2: - Instead of doing do_div in drm_print, make rem_nsec u32 (Ville) Link to v1: https://patchwork.freedesktop.org/patch/msgid/20191106173622.15573-1-sean@poorly.run Fixes: 12a280c72868 ("drm/dp_mst: Add topology ref history tracking for debugging") Cc: Juston Li Cc: Imre Deak Cc: Ville Syrjälä Cc: Harry Wentland Cc: Daniel Vetter Cc: Sean Paul Cc: Lyude Paul Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: David Airlie Cc: Daniel Vetter Cc: dri-devel@lists.freedesktop.org Reviewed-by: Ville Syrjälä Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/20191106194121.164458-1-sean@poorly.run --- drivers/gpu/drm/drm_dp_mst_topology.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/drm_dp_mst_topology.c b/drivers/gpu/drm/drm_dp_mst_topology.c index 11adc4b6ccfe..ae5809a1f19a 100644 --- a/drivers/gpu/drm/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/drm_dp_mst_topology.c @@ -1507,12 +1507,12 @@ __dump_topology_ref_history(struct drm_dp_mst_topology_ref_history *history, ulong *entries; uint nr_entries; u64 ts_nsec = entry->ts_nsec; - u64 rem_nsec = do_div(ts_nsec, 1000000000); + u32 rem_nsec = do_div(ts_nsec, 1000000000); nr_entries = stack_depot_fetch(entry->backtrace, &entries); stack_trace_snprint(buf, PAGE_SIZE, entries, nr_entries, 4); - drm_printf(&p, " %d %ss (last at %5llu.%06llu):\n%s", + drm_printf(&p, " %d %ss (last at %5llu.%06u):\n%s", entry->count, topology_ref_type_to_str(entry->type), ts_nsec, rem_nsec / 1000, buf); -- 2.30.2
