[PATCH] drm/komeda: fix size_t format string

From: Arnd Bergmann
Date: Mon Jun 17 2019 - 08:55:07 EST


The debug output uses the wrong format string for printing a size_t:

In file included from include/drm/drm_mm.h:49,
from include/drm/drm_vma_manager.h:26,
from include/drm/drm_gem.h:40,
from drivers/gpu/drm/arm/display/komeda/komeda_framebuffer.c:9:
drivers/gpu/drm/arm/display/komeda/komeda_framebuffer.c: In function 'komeda_fb_afbc_size_check':
drivers/gpu/drm/arm/display/komeda/komeda_framebuffer.c:96:17: error: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
DRM_DEBUG_KMS("afbc size check failed, obj_size: 0x%lx. min_size 0x%x.\n",

This is harmless in the kernel as size_t and long are always the same
width, but it's always better to use the correct format string
to shut up the warning.
