"Added" --> "Add"? My impression is that we don't use past tense in the 
Subject and the commit message. See
"git log drivers/gpu/drm/hyperv/hyperv_drm_modeset.c".

Should we use drm_err_ratelimited() instead of drm_err()?

The line exceeds 80 chars.

Maybe we can use the below:
	drm_err_ratelimited(&hv->dev, "%s: requested %dX%d (pitch %d) "
                     "exceeds fb_size %ld\n",
                     current->comm, fb->width, fb->height,
                     fb->pitches[0], hv->fb_size);

Note: the first chars of last 3 lines should align with the "&" in the
same column. Please run "scripts/checkpatch.pl" against the patch.
