Odd, between v6.6 and v6.17 I couldn't find any ath12k changes which
modifies the caldata download path. Is it possible to share the kernel
log with ath11k boot time debugs enabled for working and problematic cases?

modprobe -r ath11k_pci

modprobe ath11k debug_mask=0x1060
modprobe ath11k_pci

No, as mentioned caldata requirement has been same since 6.6.
