I think you can break this out into a separate patch, but reword in a manner
that doesn't indicate any dependency upon your series (it can be a predecessor)

You can do that by noting:
1) currently (before your series) the QMI interface only works on LE systems
because of how it encodes and decodes the data
2) however almost all QMI data structures did NOT use endianess-specific types
for the data structures
3) the ath12k structs being modified are exceptions
4) the QMI interfaces are being modified to support BE, and that modification
requires the QMI data structures to actually be in CPU order
5) So change the two ath12k QMI struct which currently use endianess-specific
types
6) This change will work correctly with existing kernels (which only support
LE) and will also work on future kernels where BE support is added.

Then I can take this patch separately from the QMI changes.
