Hi,
I just ran into a NULL-deref in a qrts/mhi path during boot of the
x1e80100 CRD for the second time.
First time was with a 6.11 kernel (but I never got around to reporting
it) and today it happened again with 6.12-rc5.
Both times I was using the
he identifier for the remoteproc
instance. It matches the typical names used when we speak about each
instance, while still being unique.

Retry the send until intent buffers becomes available, or an actual

To avoid infinitely waiting for the firmware in the event that this
