Hi Vikram,

Thanks for sending this patch!

I just tried this on QCM6490 Fairphone 5 smartphone but unfortunately
during probe something is not quite right.

My tree is based on 6.10-rc5 plus v4 of:
https://lore.kernel.org/linux-arm-msm/20240522154659.510-1-quic_grosikop@quicinc.com/
plus your v1 series.

And then some extra patches for my device but nothing touching camss
driver.

Am I missing something?

Regards
Luca
