Of course another possiblity, which I forgot to mention in my previous email, is to keep pci_cmn.c filename but rename the functions to ath11k_pci_cmn_foo(). Though don't know which one is better. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches -- ath11k mailing list ath11k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath11k
