drm_printk is used for both DRM_ERROR and DRM_DEBUG with unnecessary
arguments that can be removed by creating separate functins.
Create specific functions for these calls to reduce x86/64 defconfig
size by ~20k.
Modify the existing macros to use the specific calls.
new:
$ size -t drivers/gpu/drm/built-in.a | tail -1
1876562 44542 995 1922099 1d5433 (TOTALS)
old:
$ size -t drivers/gpu/drm/built-in.a | tail -1
1897565 44542 995 1943102 1da63e (TOTALS)
Miscellanea:
o intel_display requires a change to use the specific calls.
