Hi Biju,
I'll be merging your patch. It'll be my first time as a Panfrost maintainer, so bear me with me
while I become familiar with the process.
Kind Regards,
Adrian

OK. Thanks.
FYI, I just use the below 4 commands based on the documentation to merge a patch after the initial dim setup.
=> ./maintainer-tools/dim update-branches
=> ./maintainer-tools/dim checkout drm-misc-next
=> curl xxx | ./maintainer-tools/dim apply-branch drm-misc-next
=> ./maintainer-tools/dim push-branch drm-misc-next
Cheers,
Biju

if you find it simpler to pass a get the Message-ID than searching
