These are false positives, the copier which is used in these functions
always have input and output side, the be_rate will be initialized:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/sound/soc/sof/ipc4-pcm.c#n485
on the first iteration.
the sample_valid_bits will be initialized:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/sound/soc/sof/ipc4-topology.c#n1310
on the first iteration.
