While 'unsigned long' needs the %ld format string, size_t needs the %z
modifier:

drivers/gpu/drm/i915/pxp/intel_pxp_gsccs.c: In function 'gsccs_send_message':
include/drm/drm_print.h:456:39: error: format '%ld' expects argument of type 'long int', but argument 4 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
  456 |         dev_##level##type((drm)->dev, "[drm] " fmt, ##__VA_ARGS__)

Fixes: dc9ac125d81fa ("drm/i915/pxp: Add GSC-CS backend to send GSC fw messages")
