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=]

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./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.
