From 6f27e4c287d7bdcad1f24efcaace044617aac2f3 Mon Sep 17 00:00:00 2001 From: Lyude Paul Date: Thu, 21 May 2020 16:46:47 -0400 Subject: [PATCH] drm/vblank: Fix -Wformat compile warnings on some arches On some architectures like ppc64le and aarch64, compiling with -Wformat=1 will throw the following warnings: In file included from drivers/gpu/drm/drm_vblank.c:33: drivers/gpu/drm/drm_vblank.c: In function 'drm_update_vblank_count': drivers/gpu/drm/drm_vblank.c:273:16: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 4 has type 'long int' [-Wformat=] DRM_DEBUG_VBL("updating vblank count on crtc %u:" ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/drm/drm_print.h:407:22: note: in definition of macro 'DRM_DEBUG_VBL' drm_dbg(DRM_UT_VBL, fmt, ##__VA_ARGS__) ^~~ drivers/gpu/drm/drm_vblank.c:274:22: note: format string is defined here " current=%llu, diff=%u, hw=%u hw_last=%u\n", ~~~^ %lu So, fix that with a typecast.
