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.

I guess this adds up. Nice reduction. :)
Yup. 1% of all drm object code.

- drm_printk(level, category, "mismatch in %s %pV", name, &vaf);
- if (adjust)
drm_dbg(DRM_UT_KMS, "mismatch in %s %pV", name, &vaf);- else
drm_err("mismatch in %s %pV", name, &vaf);Could this use DRM_DEBUG_KMS/DRM_ERROR?
Rest looks good, so I can fix up if you want.
If want you change something like that, it should be separate patch.
btw: There was separate patch that also reduced object size of the drm_dev_printk calls several months ago. Never applied.
