Subject: [PATCH 1/1] drm/msm: fix %s null argument error
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")
