Series mostly refactors vchiq_bulk_transfer() code according
to Arnd's review comment from [1]:
You can also wrap vchiq_bulk_transfer() in order to have
four separate functions based on the different 'mode'
values and have them only take the arguments they actually
need.
I didn't wrap vchiq_bulk_transfer(), instead created four
differnet function, one for each mode.
This will pave the way to address his second comment:
Ideally this should be cleaned up in a way that completely
avoids passing both user and kernel data at the same time.
which is not part of this series and will be done on top as
arguments shuffling will have to fix the sparse warnings
that exists currently.
Patch 1/7 first moves the VCHIQ_BULK_MODE_WAITING logic out
of vchiq_bulk_transfer
Patch 2/7 then moves the core logic to vchiq_bulk_transfer()
which can be shared in subsequent patches
Patch 3/7 and 4/7 refactors remaining bulk transfer modes
Patch 5/7 finally drops the vchiq_bulk_transfer() as not needed
patch 6/7 and 7/7 are drive by patches, noticed during development.

Thanks for testing and especially catching the strange hang!
The 2/7 review comment will be addressed in v6 (shortly)
