#define drm_dbg_dp(drm, fmt, ...)                                       \

         drm_dev_dbg((drm) ? (drm)->dev : NULL, DRM_UT_DP, fmt, 
##__VA_ARGS__)

it looks for (drm)->dev (pointer)

struct platform_device {
         const char      *name;
         int             id;
         bool            id_auto;
         struct device   dev          <== not an pointer here
