During development of new features, we noticed some spots in the code that
could be improved based on review feedback from the initial driver series.

Also two race condition fixes, one found during stress testing and another
via code inspection.

Jeffrey Hugo (1):
  accel/qaic: Fix NNC message corruption

Pranjal Ramajor Asha Kanojiya (4):
  accel/qaic: Validate user data before grabbing any lock
  accel/qaic: Validate if BO is sliced before slicing
  accel/qaic: Flush the transfer list again
  accel/qaic: Grab ch_lock during QAIC_ATTACH_SLICE_BO
