Hi Umang,

Thank you for the patch.

Same comment as in 2/6. I expect it applies to other patches in the
series too.

Unlike the change in 2/6 that we may want to reconsider, this looks good
to me, even though it will be interesting to see what happens if we move
the vchiq core out of staging first. I expect in that case that the
headers will go to a directory under include/ (likely in
include/linux/soc/ ?), and this will be modified accordingly.

In the meantime, with the commit message updated,
