The following build error was triggered because of NULL string argument:
BUILDSTDERR: drivers/gpu/drm/msm/disp/mdp5/mdp5_smp.c: In function 'mdp5_smp_dump':
BUILDSTDERR: drivers/gpu/drm/msm/disp/mdp5/mdp5_smp.c:352:51: error: '%s' directive argument is null [-Werror=format-overflow=]
BUILDSTDERR: 352 | drm_printf(p, "%s:%d\t%d\t%s\n",
BUILDSTDERR: | ^~
BUILDSTDERR: drivers/gpu/drm/msm/disp/mdp5/mdp5_smp.c:352:51: error: '%s' directive argument is null [-Werror=format-overflow=]
This happens from the commit a61ddb4393ad ("drm: enable (most) W=1
warnings by default across the subsystem"). Using "(null)" instead
to fix it.
Fixes: bc5289eed481 ("drm/msm/mdp5: add debugfs to show smp block status")

I am not sure how the patch got titled 1/1 and not just "PATCH". It
should be just "PATCH"

My bad. I generated the patch with parameter “--numbered” in “git format-patch”, it will output in [PATCH n/m] format, even with a single patch. Will drop it for single patch next time.
Thanks,
