Subject: RE: (subset) [PATCH v6 00/10] drm/display: generic HDMI CEC helpers

Hi Dmitry Baryshkov,

Thanks for the series.

Looks like, After this patch, when I change resolution using modetest it is not working.
Monitor is showing out of range/No signal on RZ/V2L SMARC EVK connected to ADV7535.

Not sure, I am the only one facing this issue?

Modetest works fine with 6.15.0-rc6-next-20250516, where this patch series is
not present.

Cheers,
Biju
