From 4400c3a1d48f7f7863ca65d24f99ad295b37726c Mon Sep 17 00:00:00 2001 From: Wan Jiabing Date: Tue, 26 Apr 2022 21:21:26 +0800 Subject: [PATCH] drm/msm: Use div64_ul instead of do_div Fix following coccicheck warning: drivers/gpu/drm/msm/msm_gpu_devfreq.c:72:1-7: WARNING: do_div() does a 64-by-32 division, please consider using div64_ul instead. Use div64_ul instead of do_div to avoid a possible truncation.
