Hi Arnd,

Printing a size_t variable needs to use the %z format string modifier rather than %l, otherwise we get this warning on 64-bit architectures:

drivers/gpu/drm/vc4/vc4_bo.c: In function 'vc4_bo_stats_debugfs': drivers/gpu/drm/vc4/vc4_bo.c:91:26: error: format '%d' expects argument of type 'int', but argument 4 has type 'size_t {aka long unsigned int}' [-Werror=format=]

I already sent (and applied) a fix for this bug [1].

Regards,

Boris
